"There. Now all that's left is to set the bush on fire." -Indy, Staff of Kings.
I really wanted to show him using his whip here, but I didn't think it'd work.
The idea that actually got me started on the MOC was building the spring-loaded mechanism using gravity. From there, I thought of the serpent statue and the trap doors for the bridges.
The blur is usually a bad thing, but the effect came out really well here; it gets across the idea that the place shakes. (Sorry about adding the stick in the serpent's mouth suddenly- I just realised I'd forgotten it.)
This pic is quite bad; move along; move along.
Swoosh! If only I could've included the statues. Oh, well.
