I love Papervision - no secret about that and my love for Pixels and Pixel3D. One thing I did miss in the newer builds was the Camera3d hover method. Useful as it is I felt the Camera3D orbit did not do the job with much the same finesse as the hover method did. A little refactoring of the existing Camera3D class was all that was neccessary to get back a hover method.
