Global-Positioning Hair Clipper

Super-precise, automated hairstyling
  [vote for,

Everyone knows about those tractors that drive around with a GPS receiver on board and deliver the exact right amount of fertilizer to each square foot a wheat field. Why not do a similar thing on your head?

The Global-Positioning Hair Clipper (GPHC) always knows exactly where it is. Before you start, you map out your desired hairdo on a computer, telling it exactly how long you want your hair on every part of your head. Next you attach a "stationary" differential GPS device to your forehead (that way, if you move your head the GPHC will know). Then you start clipping. The GPHC adjusts the height of its clippers as you move it around. All you have to do is make sure not to miss a spot.

(If you share the GPHC with other members of your family, remember to reload your own hairstyle into the device before each use.)

Use it in TaxiCut http://www.halfbakery.com/idea/TaxiCut
This would be very useful for my TaxiCut, which did need to resurface on Tax Day [theircompetitor, Oct 04 2004]

Would be a good addition to the Flowbee http://www.flowbee.com/

       I've never heard of a differencial GPS system that had millimeter level accuracy that I'd want for somthing cutting my hair.   

       One other issue you haven't addressed: How do you deal with the fact that the hair strand you want to cut starts at a specific location, but the end you need to cut is hanging down at some unknown location? Does this just treat your hair as one big mass that it carves to the right shape? In that case it would seem like that if you got your hair cut on a day when your hair was poofier, it would end up getting cut differently than it would on a day when your hair was laying flat.
