While in NY last month, we stumbled on The collectivity project while walking along the beautiful High Line park.

This exhibit by artist Olafur Eliasson invites the public “to build their vision of a future city” with three tons of white Lego bricks. It was fun to see people building bridges between tables of buildings, rebuilding architectural features, adding words and symbols.

Today (October 12) is the last day of the project on the High Line.
