Scott has posted some video casts "vodcasts" for 3dsmax, Viz, AutoCAD, ADT and Revit.

I also noticed on Lynn's blog that Scott also co-authored a book on AutoCAD with Lynn Allen.

I am anxious to see what Scott thinks of Autodesk Impression since he is an expert in post design data presentation treatments.

Speaking of Autodesk Impression... We released a new beta to members of the Vespa beta community on http://myfeedback.autodesk.com. After the beta sites beat on it for any problems we will then update the Autodesk Labs download for a new version. There have been many changes based on customer feedback to the planned Autodesk Impression Technical Preview 3. 

Cheers,
