Now THAT is geeky!

People never cease to amaze me in how they find ways to go that little bit farther, taking something good on its own and enhancing or breaking it, depending on your point of view. I mean, never in my wildest dreams would I have considered playing the vocals part in Rock Band 2 by putting the microphone in a pair of headphones driven by a theremin (link). As an added bonus, it's that "Still Alive" song from Portal I just posted about recently... :)
