Under the twin flyovers where the A12 road crosses the River Lea navigation canal, in what was a nasty, litter-strewn dark space that you would normally pass by quickly, there is now an unusual and imaginative structure built of scaffolding poles, rope and wire, and thousands of recycled wood blocks, like a gigantic Jenga set. Located in Hackney Wick just outside the Olympic site, this is a temporary cinema that popped up only a few weeks ago, and sadly it is already coming up to the end of its last week. It was built by a group calling themselves Assemble, with some help from architects Muf (it's complicated), using partly voluntary labour and mainly recycled materials. The auditorium is made of scaffolding and scaffolding boards, but more intriguing is the construction of the adjoining cafe (pictured) where the walls are made of blocks of recycled wood threaded on to ropes, so it looks like brick from a distance, but clearly wood when you get close. There is even a children's play area with a huge selection of the same wooden bricks - I saw some six-foot skyscraper towers which may perhaps have had adult help. It's lively even in the daytime with an inexpensive cafe attracting canalside walkers and cyclists.
