Robotboy
We were invited to pitch on a viral campaign for robotboy, the ace cartoon on cartoon network. We won, and we produced a flash based robot testing lab where you and your friends get to build, look after, and upgrade a robot. The more time you spend with it, the bigger and better it gets.
Mine's already the size of 6 storey building and I'm planning on using it to take over the world.... mwwwaaa hahahahaha, ahem.
