Craft ideas pretty please

[cryptic-intent.livejournal.com]

My brother fixed the lighting fixtures in our work trailer today and has left me with several multicoloured thin plastic covered wires, which come in yellow, white, black, light blue, blue, pink, and red. I want to use them for something cool but all that comes to mind is the stand-by bracelet or some sort of jewelry. They're bendable and somewhat malleable but can't exactly bend on a dime, so to speak.
Any ideas or suggestions would be greatly appreciated! Thanks!
