This technology is pretty sweet. Im still figuring it out right now, but luckily there are a lot of resources out there. This blog thing they have has a lot of good examples of how this could be used. Once again, gotoAndLearn.com has some good tutorials out on using it. There is one where they use Blender (a free 3d program) to make the 3d object and then imports it into Flash using papervision. -Somehing I will be working on...
