Wait, that's my blog post from ages ago! Looking over it now, one thing that might be appreciated here are the generalisations. For example consider a similar puzzle except instead of a chessboard and 64 coins, you have a 6x6 board, with one die on each square. Instead of turning over a coin, you must add 1 (modulo 6) to the value of exactly one of the dice (and reorient it). What is your strategy?
