Looks like Telecom's tweet wall in Auckland Airport has a long lifespan planned. And it's not just a one trick pony! I posted earlier about how this interactive wall allows visitors to tweet answers to questions which are then displayed for all to see (read more here). The latest interactive experience provided allows visitors to "paint" on the wall using hand movements (picked up by motion sensitive cameras) or an iPad.
