Algodoo

This fan is a remix of another fan to make it a bit more interesting.
(I highly recommend you check out the original! Here is the link to the original: http://www.algodoo.com/algobox/details.php?id=240236)

On the main control hub on the fan, the switches 0-4 appear, clicking one will get the fan up to the correct speed based on the level.
To the bottom left, there is a power switch determining if the fan has power or not.
To the bottom right... We don't talk about that...

Have Fun
