Pop-up high street (in London) anyone?

I've not checked it out yet, but I just heard about this pop-up high street in Shoreditch called Box Park. I can't wait to see if it works.....This temporary use thing is really catching on. As for Box Park, Estates Gazette is a fan, but you don't need to be a fortune teller to see how it will probably end up. "Expect a big grumble from the 'cool kids' in 5 years time, when the temporary use comes to a close and the market has picked up enough for Hammerson and Ballymore to stick a spade in the ground."
