Evil Clown Generator from Scottsmind.
Start with a pre-set clown, and then change the face elements, or go Random.
Couldn't quite make a Trotsky on this one. Probably because this is an EVIL Clown generator, and the two just don't mix . . .
Now, I know you all can figure out how to use this, but there are a couple of fun ways to play with it. Each time you click on one of the feature types, that feature will change just one-at-a-time. If instead you hover the cursor over the face feature, they zip through at a million-miles-per-hour and stops when you move the cursor. So, with that bit of knowledge, if you just move your cursor from top-to-bottom, or vice-versa, you can visualize some really amusing changes there. So there.
Oh, this is all done in flash, but there is a "print" option in the right-click flyout that they left in for you - but, I think a screen grab selection is easier . . .
