I got nerd sniped by a great comment in a previous video. The idea was to make some kind of device to let blind people perceive their surroundings. The specific suggestion was to make some kind of a vest. Ultimately I ended up making an iPad case that uses the sensors in the iPad to perceive the surroundings and communicates through tactile feedback via a special hand grip. It was a fun project and turned out pretty neat.

I use a 13" iPad for all my technical drawing:
