Sticker Effects is a browser playground for one physical interaction. Drag the sticker and it lifts, curls back from the edge you pull toward, casts a shadow and catches a moving highlight; drop it and it settles with a small wobble. A control panel switches between three peel styles and tunes curl, shadow, gloss and wobble live.
Every layer comes from one PNG's alpha channel: the white die-cut border is an SVG dilate filter, and the flap, shading and gloss are the same image with different filters and masks. The curl works at any angle. A fold line is built perpendicular to the drag, the sticker is split into two clip-path polygons along it, and the flap turns around the fold with one rotate3d(), with no WebGL. Per-frame work skips React and writes straight to the DOM.
Status A no-build prototype that runs from a static file server.
Zach’s part Built the effect and the playground.
