What started off as an experiment with morphing ended up as a agreeable investigation of Bongo’s 2.0 facilities. The bug-fix of the custom tweening in the Beta 6 release came just in time to give the windmill a good swing.
A drawback is that morphing isn’t operational for trimmed surfaces. A small hole in the wings for the spindle would be the icing on the cake. An item for the wish list!
The model is Rhino 4.0, renderer is simply Rhino Render.
