GS maybe you have this .pk3 but though i can't remember the name, i do remember a .pk3 map being made that was just a bunch of different scripted moving brushes (ie. elevators, escalators, plunger games, cannon, rowboat etc) made to show different things you could do with scripting.
it think it was small sumo's webpage i got it from.
chris, go to [url=http://smallsumo.leveledit.com/tltrude/:6586c]this webpage[/url:6586c]. you want the tutorial map called exploding door (found about halfway down) it has a merry go round on it also. it's a map tut so you'll have to do a lot of breaking the scripts apart but if i remember right, the writer did a good job of seperating each script with an ID title.
