On one site we had the Metalith, a vending machine equipped to receive and dispense bitcoin. On the second site we had the Voting Machine, a retrofitted slot machine intended as performance art to demonstrate that voting is gambling.

The Metalith was a site to see, especially at night. The machine rested in a clearing on the top of a small hill, like the obelisk from 2001: A Space Odyssey, and the lights inside shined in the dark from a great distance. The slogan on the side of the machine was "Sell all the things, for all the money" and inside you could find familiar items like Milk Duds, but you could also find unusual items like bullets and drug tests. But most importantly it was a proof of concept. Bitcoin being a potentially anonymous currency, and vending machines being a potentially anonymous purchase, the existence of a Bitcoin compatible vending machine means that an anonymous marketplace like Silk Road is physically possible, in some sense, at least in the relatively laissez-faire atmosphere of Porcfest.
