Came across this site the other day... seems to output quite interesting images:

nice.

Also, I encountered it in this site with other interesting stuff.

Reminds me of a child's game. Sort of a tube you watched through and turned it around, symmetric figures appeared.
Now I think it's kitchy :-)

Isn't that a monkey?

I think you are talking about Kaleidoscope :)

@Tomoya: Yep! That's the word!
