Talented indeed. I've never understood people who can do more or less independent things with each hand (a limitation that probably has a lot to do with my failure to thrive at piano lessons, although lack of discipline may have had something to do with that).
I'm sure that broken arm is a major inconvenience for you, but it's working out pretty well for the rest of us.
(No Browny Points for me, I'm afraid, although I suspected the truth. Maybe half a point?)
I too am in awe of people who can do independent things with both hands at the same time. I can hold a screw with one hand and operate a screwdriver with the other. Or a knife in one hand and a fork in the other. Anything more complicated is either a non-starter or will probably end badly.
Here is a link to an 11 year old boy who sits down at a piano in a mall plays for 9 and a half minutes with out sheet music, crosses hands one over the other and with his eyes closed a lot.
Here is a link to a short organ music piece. This guy has both hands AND both feet going independently at the same time.
How do they do that!?
I was reminded of "Thing" when I first saw the initial clip that started this thread.
I did Google him before I made the entry. I was surprised that (according to Wiki) "Thing was originally conceived as a whole creature (always seen in the background watching the family) that was too horrible to see in person. The only part of it that was tolerable was its human hand." I guess TV technology then didn't allow filming him as envisioned.
Makes me appreciate the old saw that necessity is the mother of invention.
