For anyone who likes cell division, or bubble wrap, or has two minutes to waste, this is one of the greatest websites ever, and i think the code is clever.
Koalas to the Max
you drag your cursor over the bubble, it divides. then they divide, then they divide and so on and so forth, until a picture is revealed in dots. neat huh? There are dozens on there.
If you don't wanna reveal koalas, you can simply customise. place the url of an image after the / and separate with a "?"
like this one, which features my horse Copper.
Have fun.
