I recently came across what I believe is my newest, most favorite web site for geekware. Think Geek. They have ALL kinds of geeky gadgets and paraphernalia for the inner geek in all of us.
It's hard to capsulize the range of things they have available. They have geeky watches, geeky cubical stuff, geeky toys, geeky tools, geeky books and geeky t-shirts. You can even purchase a can of "instant snow" from them!
If you are a geek, or love someone who is, then you need to Think Geek.
