Hi Ben, I like the HoverCam? ;-) Could the SpringCam be of any use in this project? http://agit8.turbulent.ca/bwp/2009/01/22/spring-physics-powered-3d-camera-for-away3d-and-papervision/
I've formerly tried to achieve things with HoverCam and TargetCam that the SpringCam now solves. Perfect for chase-cams. J
