Stuaf will mock you.

Completion bonus:
Finish the game once to unlock the "Open House" file. Load it to be 
able to play any puzzle any of times.

Secret game:
In the bar ask the guy with the knife if you can try the game 50
times to play the hidden game.

Secret video:
Go to the television In Dutton's room at a point where you can see the
close-up view. Enter "Kellyn" to watch the hidden video.

Watch the entire video except the ending or to access any part of the house:
During the starting screen (the screen with the four skulls), enter
"Zaphod Beeblebrox", then type "Eleventh Hour". If you don't hear a 
bell, try pressing F12 first, then retyping the above.

Advance in game:
Emter to the skull load-in screen. Input the following case-sensitive code, 
with spaces as noted: Roberto Dan R Zaphod B [Space]

After you type Roberto, Stauf will say, " Duh.... that's not it Karl!".
Ignore him, heis trying to trick you. After the B, type [Space], 
then any of the following letters to get to that point in the game:

A: End of disc 1.
S: End of disc 2.
D: End of disc 3.
F: End of disc 4.
E: The "Olive In Stein" riddle, good for using the Kellyn code.
G: The very end, at the "Let's Make A Real Deal" intermission sequence.

Kaleidoscope screensaver:
Begin the game and go anywhere in the mansion. Do not move and eventually
the colors on the screen at that time will blend together as a screensaver. 
It is different from every viewpoint in the mansion.
