In what, as far as I know, is a first for Google… they are the host of an online puzzle game/marketing initiative for the DaVince Code.
The game needs to sit in a block on your Google personalized home page, so you’ll need a Google account, and to take a few seconds to set up/login to your personalized page. Looks interesting.
It’s kickass! I’ve been enjoying it for the past couple of days - just a shame it requires Flash8, and only Flash7 is available for Linux at this time :(
