Particle Magic, a Webcam-Controlled Particle Toy

Field notes

Particle Magic uses webcam hand tracking as the input layer for a collection of 5,000-particle shapes. Pinching moves an object, two-handed pulling tears it along the space between the fingers, and released pieces become sand that can be pushed or thrown before flying back into place. The page identifies two creator collections—22 shapes from Caleb and 31 from Amelia and Taylor—and says the browser experience needs no download, though play requires an account and camera access.
