Avalaible at SL Marketplace: [Black Tulip] Script - Halloween Dinner Ghosts - Rezzer Add-on

This add-on consists of two versions of the PROP script for the Halloween Rezzer script. They're designed specifically for our Halloween dinner set ghosts, or your own 1-prim items. Both of them make the ghosts show up slowly and vanish slowly when rezzed/de-rezzed, but the deco version also will show the ghosts only when avatars are close, being the ghosts invisible otherwise.
