A very cool idea. And in a similar vein, I am super-jazzed about the idea of wearable technology. This is what I've been wanting to do to my Jedi/smuggler costume for a while ... and what I'm so happy to find when I come across it occasionally, like with Swarovski's USB jewelry.
Why has it never occurred to me that two of my passions might end up fused into a marketable profession?
Extreme DOH!!!
Now I have a more legitimate-sounding excuse to go back to school for fashion design ... ;D
