anyone see 'trick of the mind' - that zombie game stunt was nuts

for those that didn't - derren brown (and some programmer) designed a
zombie shoot em up arcade game which they put in a pub. eventually some
guy came and played the game, and derren brown controlled it behind the
scenes so that it kinda hypnotised him to sleep.
they then moved the guy into a deserted building the game had
replicated, put a gun in his hands and sent in loads of zombie actors.
they guy went nuts, screaming and shooting the zombies - basically
shitting himself. they eventually went in to intervene, put him back to
sleep and dragged him back to arcade machine. when they woke him up he
was like "wow, that was a cool game"
