Geoff Marshall tweeted about it, and so will probably have a video out at some point. I wanted to go and see it but unfortunately wasn't able to.
Geoff posted this tweet - which points to a rival way to travel - but only for those who like their atoms scrambled during the process - and trust that they will be reassembled in the correct order afterwards!
you describe a journey on the underground well, but what happens to you if you use a transporter?
Ah now thats a good question... your atoms are scrambled by the transporter and beamed from a to b. Then you must hope that they will be correctly reassembled afterwards.
I actually ask in the film why anyone would want to use a transporter when they can travel on a London Underground tube train? Its right at the end of the film, mere moments before the train doors close and I set off for my journey home.
The film can be seen below, as I am hoping that some people from outside of London (even overseas) will watch it I added a couple of street scenes to help people who do not know London to gain a sense of the location of this station.
