The sketchbook.com site shows a promotional video which actually has very little to do with Autodesk:
it's a very inspirational video, featuring
Jay Shuster (imdb link), a designer who worked on
Star Wars: Episodes I & II,
Cars 2 & 3 etc etc. Also a fascinating story of a boy's introverted obsessions with mechanics and design -- and 'kit bashing' (making models from multiple kits), and how these evolve into a rewarding career.
