curtwoodward writes "Long before Steve Jobs kicked off the modern mobile gaming revolution with the iPhone, a Harvard astrophysicist got kids obsessed with chasing electronic lights and sounds with their fingers. Bob Doyle was the inventor behind Merlin, and built the early versions with his wife and brother-in-law. As the more sophisticated cousin of raw memory game Simon, Merlin offered games like blackjack, tic-tac-toe, and even an early music program. Doyle, now 77, got 5 percent royalties on each sale, money that paid for the rest of his projects over the years." Using those royalties, Bob Doyle spends his time writing things online.
