The guys at Channel 9 have come up with another brilliant video interview - this time one of the developers on the Avalon team (Daniel Lehenbauer) walks us through what Avalon is and how you would assemble and render a 3D enabled windows application. Avalon will ship as part of WinFX and will be available on Longhorn, Windows XP and Windows Server 2003. If you've got 25 mins and wanted a primer on 3D modelling and our support for it I'd highly recommend this video.
