Autodesk Sketchbook Pro has been a popular product for Autodesk.
So years ago when a few of the software developers suggested to our CEO, Carl Bass, that they make a mobile version of it, Carl said "That's the dumbest thing I have ever heard. Who would want to finger paint on a tiny iPhone, but go ahead." Thank goodness Carl is open to innovation. Sketchbook Mobile has been wildly successful. It's a really popular download for iPhones and Androids.
In this regard, the Autodesk Gallery has some panels that display the works of some of customers and employees who have used Sketchbook on various platforms.
"I feel sketchy, oh so sketchy..."
Sketching is alive in the lab.
