Saw it at a used computer store on one of thier widescreen LCD's but didn't have time to ask them where they got it.

It's not the regular soap bubble ones that are everywhere. This one has different colored bubbles which are transparent as you can see your regualr desktop through them and they pop and respawn.

It was very cool and all I have found so far after 40 minutes of searching are loads of the usual waterfall, space and fish screensavers. Not having much luck finding any good 3d stuff.
