One hundred Skeletons can be projected onto a building appearing to be crawling up the side!

Additionally, there are several scenes with Skeletons wreaking havoc inside a room, knocking things over, smashing out a window, even attacking a person and knocking him to the floor! Using the included virtual 3D effects versions will give your graveyard set the coolest effect you ever saw– Using a 4000+ lumen projector you can create a 3D graveyard with skeletons, ghouls, cats, ghosts walking/crawling in the yard or floor, below a 10-20 foot viewing point such as a deck or balcony. [no 3D glasses required]. Smaller scale 3D Skeletons are also included for garage floor-sized areas.
