Just got back from Danger!Awesome, where I got to burn some wedding paraphernalia with laser beams! It's fantastic to live in a city with a walk- in laser-cutting shop. And the guys who run it (a few MIT alums, naturally) are pretty rad.
The particular machine I was using had previously been used to burn 2,000 pieces of toast for a stop-motion OK Go music video. My project is not nearly so ambitious (or edible).
