I had the honor of working with a great sketchUp team out in Boulder. We
worked on several design aspects of SketchUp, including a way to "swivel"
to spin models on the web page. The video below shows a very early
prototype (the rotation is backwards).

I also worked on several 3D warehouse designs with the team. We were
striving to model a catalog and to provide more social interaction. These
are some of the mocks that we collectively developed.
