Default laser spirograph tutorial

hey guys this is my spirograph for my 100 mW green. (which hasnt arrived yet but ill post updates when it does!)
its very simple, gets the job done, i havent added potentiometers yet but i will.
what you need.
2 *12V brushless cooling fans (radioshack)
2 *4XAA battery holders (radioshack)
1 switch (radioshack)
foamboard (or any other houseing and base material, its your call. i like foamboard the best!)
hot glue
solder

the whole project comes out a little over 25 bucks.
the thing that kills you are the motors they're 12 bucks a piece.
i know i shouldve taken pics as i built it but i didnt realize i tried to paint them as best as i could.
please post comments and replies. tell me what you think!
I tested this with a crappy led light and it works beautifully i just need my laser to post some really nice pics.
thanks

ps. i apologize for my aweful setup of all the steps. hope you understand.
thanks again
