I went to next city vanguard conferece which was a 7000$ project contest, tonight and the batiment 7 group won. I'm not quite sure I fully understood the concept, it was either a table or bench spawning a few hundred meters long zigzaging around the batiment 7 area. The table or bench is supposed to look like a train track to symbolize a place of gathering for what was always cosidered a division in the neighborhood. Pretty cool idea, I find.
