Wonder what the technology you are going to be able to buy and use 3 to 5 years from now might look like? Visiting the SIGGRAPH Emerging Technologies exhibit each year should give you a pretty good idea, and this year there are a few particularly interesting ones collected on this video out of the 26 on the floor. The annual event ends today, and I wish I could have been there; perhaps next year. The other SIGGRAPH paths I enjoy are the Art Gallery and the Studio, so I am also including their trailers for this year.
