We're not so lucky. Gloucester Road is one of Platform for Art's showcase stations and the caravan and mattresses are art installations. As it's quite a recent installation, currently there doesn't appear to be any information about the artist or the statement that the installation is making. As Michael said, it's all a bit Tracey Emin with her un-made bed and tent. Way too derivitive in my opinion. Or maybe that's the point. Perhaps we're being asked to question Emin's art. Maybe it's a playful pun on the signifcance of travellers exchanging a commuter lifestyle for one that's more free and innocent.
In any case, I wonder how many enterprising homeless folk will try to nab the mattresses during the installation's run?
