Aaaaaahhh, MONSTERS!
Don't worry, these monsters are friendly...I think.

Just like those crazy arm-flailing inflatable tube men seen at outdoor events, make your own scale variant with a reused computer fan, and some multi-coloured blinking LED's. This monster is sure to brighten up any space and maybe even spook you, too.

This project uses an interchangeable thin plastic sock as the monster. You can make a few different socks and have a monster party, or you can replace the inflatable plastic sock monster with strips of fabric and create a faux fire, like this one.
The principle of air current and LED's are the same.

This is a very cool and simple to do project. I am surprised to see only 3 other comments at this time.

We have a few dozen old PC case fans lying around at work... and a half dead hoover. Are you thinking what I'm thinking?
Reminds me of Clacifur! :D
