redbrunja | Dr Not-So-Horrible

Okay, so, one of the really fun things I did at Norwescon was going to the Dr Horrible Showing & sing along. It was very fun, only now I have all the songs stuck in my head (and I SO need to get mp3s, so I can listen to Brand New Day and Slipping at the gym).

So.

There was someone on my flist who had a great icon of Dr Horrible with his death ray and the text 'Science has gone mad.' But who is it?

Help.
