Liquid Crystal Tie

This is a project I took the time to design. The principle is simple: Track the owner with a GPRS high-speed radio. The radio tracks location and compares this data to a database built and maintained by an advertising agency.
The agency updates the database using a system of auctions that occur constantly where advertisers compete for the ad-space on the users.
The company then uploads images to the memory on the ties micro controller.
The user then recieves a big fat paycheque for the work they've done.

Potential problems: users may not like having a company which is hardly impartial knowing where they are constantly, however I imagine it will be more acceptable once CCTV in urban areas really starts to ramp up.

Of course the user shouldn't be entitled to a cheque when they just wear the device around their home, so location tracking is a necessity.

Finally, the user could also drop the tie off in a downtown dumpster and rake in the dough so a measure will have to be initiated where every week or so the device needs to communicate with the users personal computer to receive an 'update' that tracks the user as active.

The potential for this kind of marketing scheme is massive and once flexible OLED technology becomes commercially available I hope this will become more realistic. It will also afford the ability to have, say, a full color display surrounding a simple t-shirt, effectively turning our troubled, fashion-centric youth into cheap, reliable full-motion billboards. As it is now, the technology is cumbersome and somewhat delicate, but this will not be the case for much longer.
