I was reading a small book I have on Escher after seeing the talk about him in this forum. There is a wonderful drawing by him of a hand, (his own right hand), holding a spherical mirror.
At the same time I was wondering what to do with a great title I have, and have had for some time, so I combined the two in a crude homage to Escher.
(Again posted else where by mistake and repeated here).
