RFID Rube Goldberg device

London design firm Berg (formerly Schulz and Webb) is working on a series of provocative videos exploring "designerly applications for RFID." The first one is this lovely Rube Goldberg machine running on RFID: "With RFID it's proximity that matters, and actual contact isn't necessary. Much of Timo's work in the Touch project addresses the fictions and speculations in the technology. Here we play with the problems of invisibility and the magic of being close."
