A variety of building materials filled the Construction Zone (in the Media Lab's Cube). Everyone was encouraged to join in the building activities. The Construction Zone featured some new Media Lab technologies. The Construction Zone remained open until 10:00pm on Saturday.

Sand Castle Viewing
In the spirit of sand-castle exhibitions on the beach, there was a special session at the end of MindFest (2:30-3:30 on Sunday) when everyone showed off projects they built during MindFest.
