You can also have walls which open/close depending on the monster's position, I think an example of this is in CSB, I can't remember where

but there are skeletons in the area, y'know the one I mean... I have also created a puzzle which has a series of doors which "laugh",

though as not to be too evil, I have put a space in between each (for now

). <p><font face=arial>Ian Clark
