Music visualizer, one of the better ones. PowerPC, iTunes, OS X. iGoom v2 comes also with a standalone "Lab" applet. v1 can have compatibilty trouble with some OS X + iTunes version combinations, but the timeless v1 look is worth seeing.
This was created by a group calling themselves "iOS" (because, the guy's name is "Borios"?) almost ten years before Apple took over the name. You'll need WayBack Machine now just to find these guys. Source code and windows/linux versions are available.
