Haha this is awesome. In 2009 Ami Clarke set up a contemporary art space in Hackney Downs. Nothing unusual there you might think, except for the fact that it's not in an old Victorian terrace or some dilapidated warehouse, but on platform 1 of Hackney Downs overground station.
With exhibitions, talks, a reading room and a regular programme of publications, banner Repeater is a strange but valued addition to the area - credit to Hackney Council for letting this one fly.
