I watched a video about magic and it was really cool. There was a guy named Marco  and he had a really cool board, so that if he drew on it the person or thing came to life and actually did human things. He also had had a video about  three i-touchs and the i-touchs talked about deceiving one another.The Magic of Truth and Lies (and iPods)--http://www.ted.com/talks/marco_tempest_the_magic_of_truth_and_lies_on_ipods.html
