Browser toys to play with
The toys corner of the catalog is the most experimental — apps where the point is to fiddle and see what happens, not to accomplish a task. Generative pieces that respond to your cursor, physics tinkers, sound visualizers, particle storms. Some take fifteen seconds to grok; a few will hold your attention for an hour. Free tier covers two at a time.
An interactive particle sandbox. Drop sand, water, fire, and more and watch elements interact in a mesmerizing physics simulation.
