I have a very hard to find official Stern Batman66 projector topper for Batman66 premiums avail for $1300. Free delivery to York show if you are going.
The topper projects a large Bat Signal onto a nearby wall or ceiling. Being the official Stern topper it has 2 node boards and a projector relay board inside of it to trigger the Batsignal projector to turn on and off approriately during gameplay.
If you have the Stern Batman66 villains topper already, this projector is designed to fit behind it as well so you could have both on the same machine.
If you have one if the homebrew Batman66 batmobile toppers you could use the node board signals from this topper to also activate the batmobile topper appropriately during game play instead of just being on all the time.
A longer power cord and magnetic base have been put on the projector itself so the projector is not restricted to only being mounted on the topper itself. This way you can place it anywhere you want on the backbox which gives you greater flexibility to get the size and location of the projected signal just the way you want.
