It wouldn't be that difficult to program.

Animating that on the other hand... Not to mention getting it to look right, yeah that would be an interesting beast. Still... Cryptic should try and harness it, but they seem to be afraid of trying "New Stuff" like this. They dip their toes in it from time to time, but they need to throw themselves whole hog at it! Otherwise this will never be anything but a moderately successful backwater licensed MMO.
