Generative Art with Random Walks
Move your mouse around!
Up/down arrows to increase/decrease the size of the grid cells (from 1px to 10px ; default = 2). - Try hitting "up" once or twice for a nice pixellated effect!
Space key to toggle automatic mode, where the emitter follows a sinusoid rather than your mouse.
Just a little script to play with random walks.
The color of a particle depends only on its starting position.
Space is toroidal.
Thanks to @s_federici who came up with the idea of switchable cell size.
