Animated Multiple Prims

There are products that can be purchased, but it seems that there ought to be a set of code posted here that allows multiple prims that rotate or move in a direction to be easily linked to another set that are stable. So many things in SL seem to be a mixture of animated prims and stable prims, but I can not find a simple way to link mine other than soft-linking which is a temporary solution it seems to me. Examples might be:

A: Drawers with bottoms (two prims) moving on touch in and out of a three prim desk
B: Three prim rotating light (warning light) attached to a 5 prim construction barricade.
C: A cushioned 8 prim swing with pose balls is attached to a four prim frame.

any variation of multi move will work for this (and it's on this forum somewhere) as well as several of the simplified solutions posted here as well

my solution has usually been to have the drawer broadcast a link msg which it also hears, upon hearing it, all related drawer parts trigger a move. just make sure to account for current rotation or it may 'open' in an unexpected direction when rotated.

I have built 'soft linked' draws, where it's really a seperate object, so that I could toss my drawers on the floor... the scripts are simpler, but the packaging is more delicate. I'd reccomend this method for high prim drawers, less chance of one piece of the drawer lagging and ruining the effect.
