Electric Rain just sent out a note to say that they've just released a new version of ZAM 3D. Those guys are doing some awesome stuff - if you've not seen their application before, it's a sophisticated 3D model editor that you can use to export to XAML. If you've got the September CTP of the WinFX Runtime Components on your machine, you should check it out. If not, have a look at this video to see some demos of what it can do, including an Xbox controller, a prototype MSN experience and a Motorola RAZR demo. Pretty cool!
