Terminal Computers from Penumbra Black Plague

[FlawlessHappiness]

I've been thinking about doing this by having the player in a room with a giant billboard as a screen.
The player would be forced to look forward. Very close to the point where he is looking are 4 areas.
Like this:
..||..
||x||
..||..
If the player looks up, the mouse will move up a little bit, and the player's look is forced back to the default position (Probably by teleporting, since it defaults the vision).
There, should also be an area in the middle, so that the player can click on stuff, if he wants to.
