Sometimes, you just need something simple to pick an animation to play.  Here’s a script to do just that.  Rez a prim, drop this script in it, and a bunch of animations, then take and wear it as a HUD.

When you touch it, it will offer you a dialog where you can play any of the animations, or stop the one currently playing.

Note the links to the included scripts.  If you don’t use the Firestorm preprocessor, you can get the source for the #included bits by following the link in the comment next to the #include.  Just cut and paste the code into the top of this script, replacing the #include.

#include "dialog_plus.lsl"  // see the source of dialog_plus.lsl
#include "privchan.lsl"     // see the source of privchan.lsl
