Errr.... the dynamic maze? I think I might have infringed on someone's copyright or something; I didn't know there was already a dynamic maze. hehe
My dynamic maze is just a little script that spawns a large, empty, low-ceiling room made out of iblocks, then fills it with w64gatedoors in random positions facing random directions, then spawns reward packs randomly inside the 'maze'. The idea was to prevent people from "learning" where the packs are hidden (this became quite a problem with my other maze-themed quests).
However it was only mildly successful, it looks more like a smattering of random walls than a maze. Still pretty popular though. If you've ever played the game Rise of the Triad, you'll feel right at home in it
