Great post. I watched these with my 5 year old last night & he was in awe. He now wants to be a Lego designer!
I thought it was interesting that they were doing some of the 3D modeling in Rhino. Given that the forms are usually rooted in more pure geometry, I would have assumed they used a parametric modeling package for everything. I was also surprised that they hand sculpted and then scanned the dog. That seems like something that could have been completely developed in CAD and forms checked through 3D prints.
