I designed a couple of T Shirts a while back, and a few of them seem to be enjoyed by people. One of those was this T Shirt based on the answer to life, the universe and everything, from the Hitchhikers Guide to the Galaxy.

As I said, this a slightly geeky T Shirt, but if you know someone who knows about computers, 1s and 0s, and (obviously) The Hitchhikers Guide to the Galaxy, then I suggest this is the T Shirt for them.
