Thanks for your comments Tim. I didn't download your vid because it is too big and my computer time outs when it downloads for too long. Maybe if you were to cut your vid it up in segments it might make downloading a little easier. I have been fasinated with 3d pics (anaglyph & stereoscopic) since I saw an IMAX film early this year. I am not sure about the theory or technology of holograms. I'm curious do they use lasers to creat them? Anyway now that I have learnt the theory of anaglyph and stereoscopic still pics I want to work on 3d video and animations. It still gets confusing when I say 3d. Is it 3d or 3d? Who knows? That is the question. 3dfilmdag
