The various blog articles on the Autodesk Design Review 2008 navigation wheels has prompted lots of emails expressing delight at what we have done; however, one suggestion was that we also provide something game-like instead of reinventing the wheel. :-)
Though we'll never implement a BFG9000 interface, we appreciate the feedback to offer additional ways to provide user interfaces to design data. I have passed your suggestions onto our Product Designers. The most direct route to making these suggestions is registration on My Feedback at Autodesk and participation in our many beta programs. Thanks for the feedback.
