Simone Giertz on why we all should be making useless things

Donning a rad vest made with googly eyes, Shitty Robots' inventor extraordinaire Simone Giertz (who recently announced she has a brain tumor) makes a solid case for creating "useless" things in a TED Talk (!) she gave in April.

In this joyful, heartfelt talk featuring demos of her wonderfully wacky creations, Simone Giertz shares her craft: making useless robots. Her inventions -- designed to chop vegetables, cut hair, apply lipstick and more -- rarely (if ever) succeed, and that's the point.
