I just got in from my daily trundle (I got slightly lost in Thamesmead) and came across something fascinating. People can apparently now play some kind of James Bond-based roleplaying game where they walk about central London responding to text messages and answering clues. Calvin Dyson goes into detail about it here. It sounds like fun, and I might give it a try one day, although for the time being I’ll probably just stick to following my nose.
