Test Bed 1

I've been walking past this sight in Battersea on a fairly regular basis for almost seven months. The large lettering always looks so dominated by the even larger spaceship building behind it.

I've never been inclined to ask anyone what the lettering was about though I've always felt a mild curiosity towards it. Anyway it finally got the better of me today and I did a bit of Googling and discovered it's an art centre. Maybe next time I'll drop in and find out what they're up to at Test Bed 1.
