I quite like the idea of having lots of easily accessible data about myself. Fitness and biological data can be a big help in organizing and optimizing one's life, and I think everyone should have access to that data about themselves. I want something really thin and somewhat modular that can collect a lot of the data I want to have access to.
LucidBand hasa flexible solar cell and everything but the display in the wristband! The only thing in the face is the display - everything else is on a pcb built into the bottom of the wristband (under your wrist). This lets the face be really thin - hopefully around 7mm - and also allows operation without the display (think: ankle band). The band will be cast out of a semi-flexible clear epoxy or something.

BOM cost for 5 boards with shipping to California turned up to be around 150$. I'm guessing parts for only 1 board would be around 100$ with shipping.
