Spotted on my journey from the Darcy Building yesterday. Following further investigation I discovered that it's a live project, known as the Playful Pavilion, designed by students from Montana State University and Oxford Brookes University to engage the public in examining spaces for sport. A response to the London Olympic and Paralympic games. It moves to London on 21 June, so plenty of time for lots of ping pong. It should be well used at the University Open Day on 9 June!
