I can’t pretend to know what’s going on under the hood, but Fluid Simulation with Turing Patterns is a relaxing way to bend your mind for the next 30 seconds. Fire up your favorite Grateful Dead track, double click anywhere to get rid of the text overlay, and then start moving your mouse. Trippy. Click here to see it in action. (Note: Requires Web GL. Simple instructions on how to install it for Safari.)
