This thread needs a big bump. PLEASE PLEASE PLEASE VOTE FOR THE HORNIMAN. The last project this company did (the Rain Room) finished last week at the Barbican. It was free but there was a permanent 2 hour queue to get in, except for the final weekend when it was longer than that. I've no idea if it was good or not because I was put off by the queues and didn't see it. http://www.guardian.co.uk/artanddesign/audioslideshow/2013/feb/26/barbican-rain-room-audio-slideshow This is our chance to have an exhibit on our doorstep, at the Horniman. It's worth 2 minutes of your time to register and vote, so please. Use the OP's link at the top of the thread to vote. It's a bit confusing at the end when you have to drag and drop the icon thingy, but please persevere.
