OhGizmo just featured this modified park and bus stop bench from designer Martin Nicolausson. Apparently, the designer is on a mission to encourage strangers to communicate in public spaces, and he figured that by turning seats into seesaws, anyone who wanted to sit comfortably would need to talk a stranger into balancing them out! It's a pretty fun idea, though I can't imagine it's coming to my neighborhood anytime soon. Link via the always entertaining OhGizmo.
