The thought had occurred to me. Then I finished this one, and realized how much of a nuisance it is, and decided it probably wasn't worth it. (Forget the materials - the hardest part was levelling the plain!) I must admit that it IS tempting, however, to throw together a hedge maze of sorts. (Perhaps with portals!) With future updates, I may well come up with some puzzle designs that will benefit from the medium.

Incidentally, if anyone out there has Minecraft: Xbox 360 Edition themselves and would like to see this live (pun intended), send me an email and I'll see what I can do.

Fun fact: the random seed for the world I built this in is 'Sudoku'. There is a MASSIVE network of natural caverns JUST below the surface in this world; in fact, there's a single dirt block somewhere north of the top-right corner of where the grid is that is all one has to dig to open up the whole thing for exploration, no tools required. - ZM
