At the moment I'm talking with Marius Veltman. He has a really awesome tutorial and technique about how to do Video Mapping or a Augmented Reality experience. We are talking about doing a project together for the Cannabis Cup here in Amsterdam to really freak out some people together with the guys form Hemp Works. Just have a look at the experiments that he has made. And get excited. It is a new technique which some have been very good at. However up until now only Marius has shared his findings and techniques. Most are keeping their cards very close to themselves on how it is achieved. Just check out his site where there are also documents about how to do it yourself. Very cool Marius!
