Interesting. This guy is like my twin in New York. I too have an ambient bus tracker (http://blog.jgc.org/2012/03/ambient-bus-arrival-monitor-from...) and an SDR/ADS-B/Pi set up that shows the Heathrow arrival flying over my house (or at least not so far away).

If he's built himself an Arduino 'games console' that fits inside a can (http://blog.jgc.org/2011/05/playing-pong-on-pair-of-candy-ca...) I'm going to be creeped out.
