This site rocks! If I could afford it, I would buy everything they have to offer! From coffee mugs with the molecular structure of caffeen printed on them to the Wifi detecting t-shirts, everything on this website appeals to me! Now if only I had enough cash to blow on all of these things! (My iPhone kind of killed my budget for the year!)
There is even stuff for girls on there. I found the 403 Forbidden range of panties quite funny, maybe my wife will be getting some geeky stuff for christmas too :P
