Feb 19, 2011: Identity-preserving ski mask

[Undertoad]

Ah, the ski mask, or balaclava. It's the ideal thing to wear in the extreme cold, because it protects your entire face and head, where most of your warmth is lost.

But wearing one, you have the problem that every cop on the street expects you to dodge into the next bank and rob it. And when you say hello to friends, they think you're a scary person about to do them harm, not the friend they hoped to see.

Above, the solution: the self-portrait ski mask. Developed by Andrew Salamone, from his own face, and "printed" with a hacked knitting machine.
