If the world consisted entirely of geeks, I think money would be abolished and the only medium of exchange would be T-shirts. Geeks just can't get enough T-shirts, the weirder the better. (The best one in my collection is from the Icelandic power company ... it has to be seen to be believed.)
So when MakeItLabs launched a fundraiser to help it do the work required to reopen its "hackerspace" in Nashua, it decided to sell a T-shirt, shown above. They cost $20, payable when you go pick it up. If you're interested, check the website (makeitlabs.com). The operation, first of its kind in New Hampshire, has to do various work on the former foundry where it's established in order to get occupancy permits from the city.
They say: "All proceeds go toward the wow-renovations-cost-a-lot fund".
