Since Rai wants some comments, I'll post one thing that I've been thinking for a while. It's speculation, but makes some sense:

big Magical things (with exception of Lacrima, that can also be used by non-Mages) only appear when he's around. In his day-off, regular structures were used. Also, the things seems to appear at his will, often after the explaining of rules. It's hard to believe that there's someone watching him all the time and matching the time of creation. Also, small objects appear in his hand in a very convenient time and in a very specific place. Not mentioning that he appeared in a giant hologram and, some few minutes later, he was inside the floating labyrinth made of buildings.
