Gradient Horse: the website that parades your drawn horses

Gradient Horse is a single-purpose website that asks for one thing, a hand-drawn horse facing right, and then sends it trotting across a slowly shifting color gradient alongside horses that other people drew. It is worth a look because it turns a throwaway doodle into a shared, animated parade, and because it does so with a straight face and almost no instructions.

The site lives at gradient.horse. There is no account, no score, and no finish line. There is a horizon, a gradient, and a procession of lopsided horses that never stops moving.

In brief

• Draw a horse on a small canvas, color its body and legs, and it joins an endless parade across a gradient background.
• Click a horse to make it hop forward, double-click to banish it, and press Horse Amnesty to bring banished horses back.
• Drawings are screened by a tongue-in-cheek filter the creator calls Artificial Goose Intelligence, which hides pictures that do not look like horses.
• It was built by designer Michail Rybakov and reached the front page of Hacker News in February 2026 with more than 300 points.

What Gradient Horse actually is

Strip away the charm and the mechanics are simple. A full-screen gradient sits behind an invisible horizon line. Horses walk left to right along that line in a loop. Each horse is a drawing, either one a visitor made a moment ago or one pulled from the pool of horses that earlier visitors contributed. The result reads less like a game and more like an aquarium, something to leave open in a tab and glance at.

The gradient is not a backdrop so much as the whole mood. It drifts slowly through a wide range of colors, so a scene that is warm and sunset-toned one minute turns cool and oceanic the next. The horses do not change, but the light on them does, and that is enough to keep the view from going stale. A visitor who leaves the tab open for an hour will see the same procession under a dozen different skies.

The site states its own origin plainly in its about panel. The gradient came first. Horses came second, as something to put on the horizon so the gradient would not feel empty. Because the maker could not draw horses, the drawing was handed to visitors instead. That inversion, the creator admitting a limitation and turning it into the entire premise, is the whole joke and the whole design.

Nothing about the page tries to retain a user. There is no streak, no login wall, no newsletter prompt baked into the flow. A visitor can draw one horse, watch it find its place in the line, and close the tab without having given anything away. That restraint is rare enough now that it stands out.

How to draw a horse

The drawing panel opens on a small canvas, roughly 350 by 280 pixels, with a single printed instruction: the horse should face right. A tiny horse emoji points the way in case the words are not enough. There is a brush-size slider that runs from a fine point up to a thick marker, so a horse can be a careful sketch or a few confident blobs.

The color picker is where the toy hides its one real trick. A drawing is split into three parts: body, hind legs, and front legs. Each gets its own color. That split is not decorative. It is how the animation works. The parts painted with the leg colors are the parts that move when the horse walks. A visitor who understands this can make a horse gallop convincingly, or can cheat the system in useful ways.

Coloring for motion

On Hacker News, one commenter shared a practical tip that the creator endorsed: a tail or a head drawn in a leg color will animate too, because the site does not know a tail from a leg, it only knows which pixels are told to move. Someone used this to draw a Pegasus whose wings flap. The lesson for anyone drawing is that the three colors are less about anatomy and more about which pieces of the picture should wiggle. Those public tips sit in the Hacker News discussion, which is the clearest unofficial manual the toy has.

None of this is explained on the canvas. The site trusts people to experiment, and the experimenting is most of the fun. A first horse is usually a disaster. A third horse tends to walk.

The parade and its small rules

Once a horse is submitted, it drops onto the horizon and starts walking with the rest. The line is the whole show. It moves at a calm, steady pace, and the gradient behind it keeps drifting through colors, so the scene never looks quite the same twice.

A few gestures give a visitor a little authority over the herd. A single click or tap on a horse makes it jump forward with what the site describes as joy. It is a small, silly reward, and it is oddly satisfying to poke a passing horse and watch it hop.

A double-click is darker. The about panel puts it bluntly: double-click a horse and it falls off the face of the earth, never to be seen again. That is the site's own phrasing, and it is the kind of line that makes a one-page toy feel like it has a personality. The banishment is not quite permanent, though, because of the next button.

Horse Amnesty

Tucked into the about panel is a button labeled Horse Amnesty. Pressing it brings back the horses a visitor had banished, a clean undo for a cull that may have gone too far. The naming is doing a lot of quiet work here. A plain reset button would be forgettable. Calling it an amnesty, as if the horses were prisoners awaiting pardon, is the sort of detail that separates a toy someone cared about from a toy someone shipped.

Together these three gestures, hop, banish, pardon, are the entire interaction model beyond drawing. There is nothing to master and nothing to lose. That is the point.

It is worth saying what these controls are not. There is no leaderboard of most-clicked horses, no counter of how many times a horse has hopped, no way to follow a particular horse or claim it as yours in the parade. The site resists every obvious hook. A visitor cannot even reliably find their own horse again once it blends into the line, which is part of the charm. A horse is given to the parade, not kept.

Artificial Goose Intelligence and the moderation joke

Any site that lets strangers draw pictures and shows them to other strangers faces one obvious problem. People will draw things that are not horses, and some of those things will be rude. Gradient Horse addresses this with a filter it jokingly brands Artificial Goose Intelligence. According to the about panel, each submitted drawing is analyzed, and anything that does not look sufficiently horse-like is filtered out of the default parade.

The creator, posting on Hacker News under the handle spython, explained that the AI-assisted drawing moderation was inspired by drawafish.com and works well at keeping the parade family friendly. Drawafish, hosted by the Monterey Bay Aquarium, is an older site that invites children to draw a fish and then animates it in a virtual tank, and it leans on similar screening so the tank stays pleasant. Gradient Horse borrows that lineage and wears it lightly.

The filter is not a locked door. The about panel includes a checkbox labeled SHOW NON-HORSES, with a warning that the unfiltered pool may include off-topic or inappropriate content. A visitor who wants to see the rejects can opt in with full knowledge of what that means. This is a sensible pattern: a clean default, an informed override, and a clear warning in between. It is the same shape of choice a visitor meets at The Bureau of Tiny Approvals, another tiny single-purpose site in the same spirit, where a small decision is dressed up as a solemn procedure.

One Hacker News commenter noted that the familiar hard part of this kind of moderation is filtering out crude or hateful drawings, and that the automated approach handles the bulk of it. No automated filter is perfect, which is exactly why the non-horse pool stays behind a checkbox and a warning rather than on the main screen.

Who made it, and why it looks the way it does

Gradient Horse was made by Michail Rybakov, a designer whose personal site is rybakov.com. On Hacker News he described wanting to make something he liked about the early web, something small, optimistic, and whimsical. That brief explains nearly every decision on the page. The scope is tiny on purpose. The tone is gentle on purpose. The whole thing could be a weekend project, and its appeal is that it feels like one.

The site is honest about being an indie art project. Its support panel offers two ways to chip in: a buy-me-a-coffee link and the option to order a mug printed with a visitor's own horses through a print-on-demand service. The mug feature is a nice touch, because it quietly reframes a drawing as something a person might want to keep, while warning that a browser restart can forget which horses a visitor made. That warning is also a small, honest admission about how lightly the site stores anything.

The music is a separate credit. A toggle in the corner plays a loop made by a project called Linear Loop. It is optional and off by default, which fits a site that never pushes. A visitor who wants ambience gets it with one click, and a visitor who wants silence is never nagged.

Small signs of care under the hood

The page source rewards a quick look, because the small decisions line up with the gentle tone. The error-monitoring script is self-hosted rather than loaded from a third-party domain, with a comment in the markup explaining that this avoids ad-blocker interference. That is a considerate choice: it means the site keeps working for visitors who run blockers, instead of silently breaking for them.

Analytics are handled by a lightweight, privacy-leaning counter rather than a heavy tracking suite, and a resource hint preconnects to the drawing interface's own back-end so horses load faster. None of this is visible to a casual visitor, and none of it needs to be. It is the kind of quiet plumbing that signals someone sweated the details on a project that could easily have been slapdash. A horse toy did not have to be built carefully. This one was.

The footprint is deliberately small in other ways too. The default view is a single scene with no cookie wall, no interstitial, and no consent gauntlet before the first horse appears. For a site that invites strangers to draw, that lightness is a design position as much as a technical one.

Why a toy like this still matters

Gradient Horse landed on the front page of Hacker News in February 2026 and gathered more than 300 points, which for a one-page horse toy says something about what people are hungry for. The comments were warm. One reader called the simplicity of the animation hilariously charming, and that phrase captures why the site works. It is not impressive in a technical sense. It is pleasant in a human sense. Another reader joked that the time between opening the page and spotting their own horse in the parade was about five minutes, a gentle complaint that is really a compliment: the queue of other people's horses was long enough to get lost in.

That popularity is a reminder that a boring website, in the affectionate sense the genre has earned, is not a boring experience. The useless-website tradition, sites built to do one needless thing with total commitment, has always traded on surprise and restraint. Gradient Horse fits the lineage neatly. Its needless thing is a horse. Its total commitment is that the horse must run, must have colored legs, and must join a parade. Nothing else is permitted to clutter the screen.

There is a small revival of this kind of making, sites that do one odd thing well and ask for nothing. They are a counterweight to the engagement-maximizing web, where every surface wants a login and a metric. A horse that trots across a gradient is immune to all of that. It cannot upsell, cannot track a funnel, cannot be optimized into something worse. It can only trot.

Gradient Horse also belongs to a tradition of collaborative drawing toys that treat strangers as collaborators rather than threats. Drawafish did it with fish for an aquarium audience. Gradient Horse does it with horses for whoever wanders by. The shared canvas is the real feature. A visitor's horse walks next to horses drawn by people they will never meet, and that quiet company is more charming than any single horse could be alone.

For anyone who keeps a list of calm tabs to leave open, this is a strong candidate. It makes no demands, rewards a few minutes of doodling, and keeps producing a slightly different scene every time the gradient turns. That is a generous amount of nothing.

FAQ

Do I need an account to use Gradient Horse?

No. The site at gradient.horse requires no sign-up and no login. A visitor can draw a horse, watch the parade, and leave without providing any personal details. The about panel notes that a browser restart may forget which horses a visitor drew, which reflects how little the site stores.

Why do some of my horse's parts move and others stay still?

The animation is driven by the color parts. A drawing is split into a body, hind legs, and front legs, and the parts painted in the leg colors are the ones that move when the horse walks. As visitors on Hacker News pointed out, this means a tail or head drawn in a leg color will also animate, which is how people make galloping horses and even a flapping Pegasus.

What is Artificial Goose Intelligence?

It is the creator's joking name for the automated filter that screens submitted drawings and hides ones that do not look like horses. The maker has said it was inspired by drawafish.com and helps keep the parade family friendly. Visitors who want to see the filtered drawings can tick the SHOW NON-HORSES checkbox, which carries a warning about off-topic or inappropriate content.

Can I delete a horse I do not like?

Yes, within your own view. Double-clicking a horse removes it, in the site's words sending it off the face of the earth. If that removal was a mistake, the Horse Amnesty button in the about panel brings banished horses back. Both actions affect only what a given visitor sees, not the shared pool for everyone.
