Post some good puzzles and recommended games with them. Bonus points for puzzles that involve more than combining object #1 with object #2. For starters, Kathy Rain had some nice mausoleum puzzles and I really enjoyed abusing that hobo. Pic extremely unrelated!
Myst would be an obvious example. Also would recommend the Room, I've been looking for a similar game for a long time, it really struck a chord with me.

Uncharted 2 had puzzles that were even more complex than BI.
Great puzzle and puzzle progression design, considering they managed to stretch out one concept into an entire game.
