Character Gallery
     When  you're in Tamahara, the Age in which the game starts, go to
Atrus'  desk.  Hold  the '~' key and click on the picture of Atrus and
Catherine  on  Atrus'  desk. A screen will show showing the actors who
played the characters in the game.

PEZ Dispenser
     When  you're  in  Saavedro's  home, go near the hammock. When you
zoom  in, hold the '~' key and move your cursor around. You should see
a zoom-in cursor. If this is the right one, release the '~' key and it
should  disappear.  Hold  the '~' key and zoom in. You will find a PEZ
dispenser,  with  the  initials  MEB on it, for Mike Brown, Myst III's
lead animator, who has a lot of PEZ dispensers.
