For something like this to work, it must be the highest quality image, full screen, and interesting to look at. This was just junk. I work in video, was trained in video arts when I went to art school, and can tell you that this video is without creativity, without imagination, and it is certainly bad art. Basically, if you put your eye to a two dollar kaleidoscope, and turned it for an hour, this is exactly what you would see. If you can find a video called "By Design" by a company called Colorcalm,you will see what a collection of great video artists are capable of doing. This video has a series of gorgeous and subtle video 'chapters', each one like a beautiful moving abstract painting. I've wanted to buy this for all my friends, but I can't seem to find even one other copy. Meanwhile, save your money on this video.
