RGB Led Spinner

i made this a while back, pretty easy, but looks great!

parts used
12V motor
pieces of protoboard
can of some sort
2 RGB changing LEDs (the ones with 2 pins)
some wire
2 switches
9V battery + clip
3V coincell

please note in the vid:
the camera isnt that great, so the flashing you see halfway through isnt really there
also, it isnt perfectly balanced (wich is near-impossible for DIY) so it's vibrating around a bit (vibrobot function!)
and becouse it's quite a short movie, you don't actually see all the different colours this baby makes. inside the LED's is a very tiny cicuit that makes the LED change colours, but theyr tiny and cheap, so not that accurate.
that way, the 1st LED will change colours after 1 second, and the other after 1.05 seconds (not actual times!) making the colours get really different after time (+5 minutes) and adding to the effect!

possible improvements;

-more leds
-drive it all from the 9V battery (slip contacts)
-balance it better

If you fix the (bottle?) down (or fill the bottom with something heavy, like plasticine), it won't spin the other way, and the whole thing should end up quieter as well.
