I saw this lady on some show years ago. I'm not sure what show, I'm thinkin maybe 20/20 or something like that. I thought it was quite interesting. She had made a human version of a cow-crusher. It was really neat. It helped her to calm her anxiety. She said the device would help those with autism because for her and many other autistic people, the world around her is kind of a sensory overload and the device helps to soothe that.
