@Joe - thanks. I had forgotten about MagicPedia.
In regards to Shrdinger's Coin, I have always believed that quantum physics and magic had a great deal in common. I am not sure how many of us understood the reference. Nice trick, anyway. The same principle is involved in a somewhat recently marketed effect that instead of relying upon dim lighting uses a semi-transparent cloth to cover coins on a mat.
