Impressive work. Like your QQ idea - think I shall steal it. Looking forward to your poor MC discovering how fun his trip really is. Oh, saw this comment about LED lighting today, thought of you: "Street lights that can be programmed to blink in front of a specific house so that ambulance crews can find it faster at night." Imagine that. No more "Crap, a T-junction! Left or right?" though with satnav, I guess it might soon become redundant.
