I found this amusing to play with. When you get to the site, try moving your mouse around to different colors and watch what happens.

Pretty wild, fun to play with!

It's fun, but I think it is not recommended for epileptic people

Wow, what a trip!

2-ton - If you want a real 'trip', try placing your cursor in the center and slowly drag your cursor out in any direction, or start at a corner and drag slowly to the center, and watch what happens.

YAFU - You are absolutely right. Just make sure you don't sit too close to the screen if you want to keep your lunch.

Odin - Yeah, I played with it for a while myself and decided to share here. A person could wear out a screen capture program grabbing a few new patterns.

woah trippin'

ahahaha, cool. Although it's hard to even find the little cursor arrow in all that stuff!

draconian: that's a really fun find you made ! i'm making screen dumps from it, don't know yet if the quality is good enough to make something of them, but i have sooo many ideas.

Well that puts my bubblewrap thread to shame.

Not possible! This one loses it's novelty rather quickly, whereas my bubble wrap addiction, I'm afraid, will never be cured.
