Last time I played JS Joust was December 2011 Festivus @ Nottingham Hackspace.
Deceptively simple, but fun to play!
Shortly after I left, Tom Scott (yes, he off the internet) got a bloodied nose via a mistimed move from a friend of mine, she was mortified and rather apologetic, he was very graceful and understanding apparently.
I believe there is a photo somewhere of Tom stood in from of the X dats since last accident counter, before he reset the count, but I can't find currently - will update if I do!.
