I got a note yesterday from someone who works on Google's 3D modeling app, SketchUp.
"We kept hearing from our customers that their children had jumped on their computers and created some amazing SketchUp models, and by the way, their children happen to be on the autism spectrum. We did a little research, working closely with our local ASA chapter, and realized that people on the spectrum tend to be visually and spatially gifted - helpful skills when using a 3D program."
So the group developed something called Project Spectrum. The goal: "Introduce people on the autism spectrum to a free tool that may be interesting to them, or play to their strengths."
