That's tricky, mainly because if you want the player to actually see each statue moving. That requires MoveObject entities, which can only move one direction. Having the statues moved instantly without the player seeing the animation makes it much simpler.
This sounds interesting. Working on a solution now - should post back within an hour or at most two

Ok so, I've made a test map. I think this should be working now

. I will be pm'ing you the solution shortly after another quick round of testing. You are going to have to tweak entities and settings and whatnot to suit your needs, but i've made this as easy as possible.
Well, shit, that was unexpected.
Anyway, Appjm you crazy bastard, thank you.

The idea for that puzzle was quite interresting to me, so i worked on a solution, too... and found one,
but apparently a bit late
