Thanks Best. A friend of mine thought of an idea for wheel chairs. She thinks they should have some kind of easy access umbrella built in-do any of them have that?
That reminded me of something. Singer Neil Young has two kids with Cerebral Palsy. He invented some things for them to use so that they can more easily enjoy remote control model trains. It is a technolgy that can be applied to many things. They can operate mechanical things with their head instead of hands.
