Installation
Without it nothing errors, but the stickers never respond to a touch.
Usage
The board fills its parent, tosses each sticker on at a random spot and angle, and brings the one you pick up to the front. Try it on a real device: a simulator can't be tilted, so the foil never shows.
How it works
Each sticker is drawn with Skia as a 16 × 16 mesh. Holding it starts a bend at your finger that sweeps to the far side, and each point rises the further the bend has passed it, with perspective so the lifted part grows toward you. The same mesh, blurred and flattened, is the shadow. One shader rides the bend with a bright crest and a dark trough so the crease reads as a crease; another adds the rainbow foil, clipped to the art's outline and driven by the phone's rotation sensor on the UI thread.
