In case you have not seen this very cool presentation done at the TED conference, check this out there : Photosynth. This is a project I would do anything to work on it. They are reconstructing the Notre-Dame Cathedral with image from flicker. Can you imagine that! Unbelievable! If you still have time to check another video, check the Tony Robbins presentation. I have read his book some years ago (his name in the french book is Anthony Robbins, translator have this crazy idea that name can be translated, by example : Buster in the Mythbuster show is called Jimmy) and he had help me a lot finding what I wanted to do in life. He is very entertaining and motivating.
