That's a neat perfectly looping gif, Heidi, and I like the other ones when I click through!

More about the artist:

Digital artist Paolo Čerić is currently studying information processing at the Faculty of Electrical Engineering and Computing in Croatia where his experiments with processing and digital art have resulted in a steady stream of fascinating animations which he publishes on his blog Patakk. Čerić tells me that he began about two years ago knowing very little about digital art or animation, but was fascinated watching other coders create art with code. For a while he simply tried to mimic other animations he’d seen, but lately has truly developed his own personal style that varies from pulsating geometric patterns to glitch art and everything in between.

This guy is impressive, here's an album I did about his pieces: http://imgur.com/a/2e7tm

A bit lazy to stash it right now. : )

Oce, great album. Looks like you stashed them about 4 months ago.
