The circuit board of this clock is rather a work of art. Impressive. I recall an old professor of mine built something similar using two hard dive platters as the base. He skipped the seconds ring though, so his only had the two rings. Never saw the circuitry behind his clock, but I doubt it was a nice as this example.
Regarding the circuit board, I find it intellectually satisfying to see that he placed the date that he made the clock onto it (8/8/1970). How many times have you opened something up and asked, "I wonder when this was made?"
The beauty is on the inside. Although the wood case is handsome, I think this would be very nice in a case that allows a view of that amazing looking circuit board.
