This is a little idea I had for a possible sequel to 'Complex'. I read about the movie Cube on wikipedia and saw the trailer, and what I noticed is that there, all the cubes are moving. I now made a very small thing that can kinda do the same. Well, for now, only the color of wool changes, but imagine 5x5x5 square rooms, getting rearranged everytime you switch between rooms. You'd go back through the door you just entered in and come in a completely unknown room!
To see what I made to do this, go in the room above the lava pool room, and walk to the room with the colored wool. Rooms stay at the same place now because it'd cost me too much time to do that, and the other rooms don't change, for the same reason, but that's what eventually'd be the idea.
The way I made this was quite easy, you just teleport to another 2x2x2 complex when going between those two rooms. The biggest problem that still bugs a little bit was making a system so you won't teleport twice. It doesn't really work out well, but I do not know a quick way of fixing this without mods, so that'd be up to you.
Oh yeah I named it Complex Complex... which mathematically would kinda be Complex² :p
This map is 1.7.2, but I think it will work in 1.7.4 just as well
The teleport system often glitches, this is because you'll almost always teleport multiple times. I couldn't find a really good way of fixing this.
I hope you'll use this idea in the future, but it's up to you of course!
