The Day-for-Night solar dress is made up of 448 white circuit boards that can be swapped out for all kinds of goodies — kinda like Batman's utility belt, but a hell of a lot sexier.
The tiles can be solar cells, photocells, RGB LEDs or even jumper connectors, and the whole thing is tied together by a microcontroller that provides power, keeps an eye on the tiles and can transmit data via radio frequencies. A USB board on the dress allows it to be plugged into a PC for programming. Tiles can also be added to or removed from the assembly to adjust skirt length.
So are women's purses filling up with enough gadgetry to warrant turning them into walking power chargers, or is this dress just a trap for nerds? I can only confirm the latter.
