I must have walked past this quite a few times before but never noticed it, cemented onto the wall of the wonderfully-named progressive arts venue The Horse Hospital.

Presumably put up last year when we were hosting the Olympics here in London, it offers the opportunity to “teleport in minutes” to one of a number of Olympic venues around London, just by inserting your Visa card and pressing the button.

But it doesn’t say what the cost is. I might have had a go if it wasn’t too dear :-)
