During AU I got a chance to see Project Newport, a product David Light describes as a gaming engine for architects, while my colleague Paal Vonka sees it as NavisWorks for architects. It's sort of a project viewer that shows rendered architectural models. In any case, here's the link: http://labs.autodesk.com/technologies/newport/
Look out for updates!
Got this link from a friend today. Apparently a friend who speaks spanish (I don't!). Nevertheless, the images are cool!
