This is probably old news to everyone, but I just discovered Flipboard, and awesome use of space and a wonderful contribution to the public realm.
Designed and built by architect Martin Heide and interior designer Megg Evans of Brolly Studios, it is a wonderful project, redefining the public space around it. The three niches which open out seem to both borrow space from the street, and to contribute a sense of protection and territory to pedestrians. And it's made of plywood. I love it.
