Here's another widgit that's really nice;

"The Warholizer".

This lets you turn your own photos into a montage based on Andy Warhol's famous pictures of Marilyn Monroe. You can see here how I look after "the treatment". I like this a lot.

The images are generated at random. Sometimes you'll get a blank coloured square; looks like that occurs when it generates a foreground and background in the same colour. Just try another one. It's quick and simple.
