EDIT: thanks everyone! Since you were all asking here’s how I did it:
- three 5k lumen projectors: garage, outside and upstairs window. You can find decent 3k lumen projectors on marketplace / offer up all the time for $100-300. Stick with major brands though like Epson though. The cheap ones are never as bright as they say
- Upstairs window: I’m wear projecting straight on the window screen with the window open
- Outside: I’m rear projecting on frames that connected with window screen material. These work great as shims, and at night they are very hard to see
- Garage windows: rear projecting on privacy film that I already have on the windows. Works great as a rear projection screen. This one takes a little bit of projection mapping kung fu to get the ghosts lined up right. But it is only one projector
- finally you need cool ghosts
