Haptic Coat For The Blind
January 27th, 2010 | researchmaterial
Fascinating. Designed by Lynne Bruning, "Bats Have Feelings Too" is a fashionable haptic coat for the blind, or, in her term, "a wearable cane."
Materials | lilypad arduino, conductive thread, ultrasonic range finder, vibration boards…
And, also at that link, a clickthrough to instructions for making one yourself.

Almost enough to make one want to be blind… not quite, but almost.
you are utterly amazing- you are so talented!!
