Dude, the hoverboards may not be true but they used a lot more than computer graphics to make those things fly. They used every trick in the book including skateboards, animation artists, moving platforms, and even suspended actors by strings. The concept of the hoverboard is something that will be real in the future. There is one company on the net that has developed a REAL hoverboard that floats on a cusion of air. I apologize to the list and moderators for this message that doesnt have much to do with the D but i feel that BTTF is a verry important film and i was offended by the post that said they just used computers to make the hoverboards fly. I am sure that BTTF is an important movie to many of us DMLers becuase of its exclusive use of DeLoreans. Steve Rice
