On the first day of the SXSW Interactive Conference, I noticed one corner of the convention center being taken over by interlocking cardboard shapes. The display morphed and grew over the four days as attendees played between sessions. Turns out, these "toys" are called Bloxes and were designed to build movable walls to dampan sound in offices and just build cool things. A case of 20 Bloxes in white or brown costs $59.95 and each Blox measures 9.5 inches square when assembled.
