heres my second idea and its of a good ol fashion Bob-Omb.

oh and to start it up all you have to do is wind it up and your good to go... jk :P to much work keeping the thing on but ya the wind up key would still wind up, it wouldnt do anything besides spin but who else could say they have a wind up comp.
be awsome to be able to walk into a lan party carrying a Bob-Omb
