Nerdvana noun: A state of total geekdom. NerdVana Shirts create shirts to cover all geekdom, from astronomy and physics to computers and gaming. I have tried to make my shirts interesting, accurate and humorous. I have started with the stuff that I’m interested in, but hopefully, in time, there will be something for every geek. Display your geekdom proudly, wear a shirt that tells people everything that they need to know.
