Interesting read - Visually directing the player

Today I'd like to point you all to a nice article I found on A Hardy Developer's Journal (Igor Hardy's blog). It's actually the first submission by Joshua Nuernberger (La Croix Pan, Boryokudan Rue), and totally oriented towards Point-and-click adventure game developers. However, some of the hints and tricks may also be used in games where there is some sort of exploration, or puzzles.

It's worth a look. You can find it here.
