I haven't really paid much attention to the clues in the past, but I probably will start paying more attention next year.

Yep.

2003: I'm not sure if this one was the official one or not, but y=ax^2+bx+c.
2004: lines from "Stairway to Heaven"
2005: riddle about amethyst glasses, two baseball players who'd made unassisted triple plays, and pi. I don't remember the exact wording; search for the thread discussing it.
2006: See my earlier post here
2007: still from the game animation, zoomed in
2008: chain going to statues, among other things
2009: Moonfish picture and a riddle

The game has been figured out once or twice, and elements have been found, but never the entire thing.
