I was recently turned onto a website that features soap crafted to cater the geek crowd: GEEKSOAP. This is the awesomeness that I saw, and instantly ordered.
From video game cartridges to a D20 on a rope, from Doctor Who to binary blocks, GEEKSOAP is sure to have something to appeal to your interests. Go check out geeksoap.net and see what sort of creations Lesley has available. You can also follow her on twitter at @geeksoap.
