WTF - Infinite chocolate generator!

[ColinJ]

I can't quite get my head round how this animated GIF works - it seems to generate a free piece of chocolate each time! (You will have to have GIF animation enabled to see it work.)

Who cares how it works, where can I get one?

That's just Tetris for the terminally lazy.

As the biggest piece slides up and to the right, watch the length of the sides of the bottom 3 pieces expand as it slides.
It's infinite chocolate generation Cadbury style...smaller and smaller bars with the same number of pieces
