I decided to watch the new demo vid's on Jay Sankey's videos, and I think they aren't as good as the original demo videos by Oz Pearlman. Even though Jay Sankey invented the tricks, I think they new videos were shot at a bad camera angle. For example, in Public transit and Snow storm, the color changes were more obvious. I went to Oz Pearlman's site and watched the original video, and they're shot at better angles.

Plus, in Public Transit done by Oz Pearlman, he does an extra convincer.

well you should email penguin and ask them is thell look into that
