WindowFX - Animated Halloween / Christmas Scene Projector
This inexpensive, all-in-one digital decorating kit includes a miniature projector, tripod, remote control, and window projection material that allows you to display realistic animated scenes of ghoulish ghosts, dancing skeletons, swarms of zombies, shadowy silhouettes of creepy monsters, and more right on your windows or wall.
The Projector Ring - There’s a transparent slide installed and a lens on the opposite side. When you send a ray of light through it the ring makes a decent projector. The built-in slides can be changed at will. Awesome!
