Aspiring Sleuths

I've had a lot of fun with Google's Da Vinci Code Quest over the past 24 days, and I'm very much hoping that I made the final phase, if only because it will give me a couple more puzzles to play; I don't think I stand a chance of winning the speed competition for the grand prize. Both the daily puzzles and the official site play a bit like a Myst game, albeit without the ingenious subtlety of the Riven chapter. Maybe I can pick up Myst IV on the cheap this summer to keep from going through puzzle withdrawal.
