Boston.com / Business / Over the edge: "11,000 Cleancut Nanobots

Designed by (Eleven)
Forget 5 o'clock shadow. The 11,000 Cleancut Nanobots are so tiny you can't see or feel them. But as you go about your daily routine, they'll scour your face for signs of whiskers and cut them off. Here's how it works. The first time you let the nanobots loose, they create a 3-D map of your face and send it to the computer. You outline on the computer where the nanobots should and shouldn't shave. You can even try out different styles before setting the microscopically tiny robots in motion.


When you want to give the nanobots a rest, you wipe your face with an electrically charged cloth designed to collect them. When you want to release them again, push a button on the cloth to switch the electrical charge and off they go. The advantages? The nanobots do all the work, there's no 5 o'clock shadow, no nicks, no chafing, and no need for shaving cream."
