Nerdy gifts for nerdy people

For the longest time I have been promising one of my co-workers that I would paint a picture for him. He wouldn't tell me what he wanted me to paint and said that he'd leave that up to me. So I decided to do this superman logo because I always tease him about being a comic book nerd. I gave it to him yesterday which happened to be his last day at work. He said he's going to hang it up in his new office. So I'm guessing he liked it ;)
