At San Francsco's Clockwork, you can now make an appointment with a robot "manicurist." Insert your hands into the robot and it will perfectly paint your nails in less than 10 minutes. Just choose your colors and the robot takes care of the rest. There is a hand rest to keep your hand stabilized "so that when the robot goes to paint, it can really create that sub-millimeter precision and allow the dispense rate of the polish to be perfectly controlled, so you're getting an even coat in one application," co-founder Radhika Apte explained. The cost is just USD $8.
