Drift Gallery

The cards drift on their own and you can grab and throw them with some momentum. What makes it feel right is the push - pick a card up and the ones next to it move out of the way to make room, and they don't just snap across, they go a touch too far and settle back, so it feels like you actually nudged something with a bit of weight.

There's also a film-style grade sitting over the whole thing, grain and a soft vignette and a bit of colour fringing that picks up when you throw the cards fast, so it reacts to how hard you drag. That grade is the main reason it's built in WebGL and not plain HTML, you need real rendering to lay that over a bunch of images and still keep them moving smoothly while you fling them around. You can pull it right back for a clean product look or push it for something grainier and more editorial.

Past that it's yours. Drop in your own images, set how fast it drifts, and dial the grade where you want it. On a phone it drops the cursor effects and just lets you swipe.
