One of our members brought this to my attention. Please log onto www.touchdrawing.com, and read about a unique artistry. Be sure to click on the video. Supposedly, it is useful therapy for early stage dementia patients. I have not had time to read all of it - I did watch the video. I can see where it would have a calming effect. In any case, I found it fascinating.
Seems like it would be great relaxation therapy for caregivers at home all day. Someone mentioned it was a way to channel anger, etc. Heck, I'm not stuck at home, but I might give it a try. You don't need to be an "artist" to do it. Could end up with some interesting "art work."
