Avalaible at SL Marketplace: [Black Tulip] Script - Halloween Rezzer - AVsitter Plugin

Rezzer with twists that will let you have your props float, play a sound, leave one of them as decoration when no one sits, and having the props change and float if needed as sitting avatars change the animations from the AVsitter menu.

Included two full perms particles scripts and a C/T particles texture that works with our Halloween table setting. You can adapt them to your own creations as well. Sound clip included is C/T.

Keep in mind that sample assets are never provided in full perms state. They're included to illustrate how to use the script.
