That would depend on the construction of course. Everything can be broken down, the question is what you get of it.
The Fibonacci sequence is simple enough to make people guessing, and rises fairly swiftly, so anything beyond ten becomes too impractical for use. You could encode something like an elevator with this, the destruction of the mechanism could destroy the whole cabin and drop the passengers down a _very_ deep hole.
the door is simply that, a door, litterly propped up against the wall if you break the door then you cant go anywhere.you can move the door. you can do whatever but if you break it then you go nowhere...
Manfred, your idea of an elevator intrigues me. if continuing along this line of thinking you could really have something simmilar to the glass elevator of willy wonka (sorry about bring him in here, but it works) where the numbers are listed as buttons but not in order of the sequence thus figuring out the sequence is impractical yet time consuming.
you could litterly hit a button in the correct sequence such as with the library on the 4th "door" such as hitting the buttons 1,1,2,3 thus entering the library. thus making higher numbers and combinations possible... Go to Comment
A huge moon, with a three-coned volcano which can be seen from the planet when it erupts and is taken for an omen. The planet, smaller than the moon, orbits it, and the planet in turn is orbited by a very small but very hot and bright ball of flame.
