Mirrored window

[thecrazylightlady]

Have been asked to do a Christmas display for the butcher shop I work in and want to do a Santa’s workshop projection in the window. Unfortunately the windows are mirrored and I have no idea if this will still work or not. Has anyone else done this and can give me some feedback please?
The projection will be from inside the shop.
Thanks in advance

My suggestion would be to do a test with an ordinary screen. Maybe have someone stand inside the shop in the dark holding a backlit tablet or laptop screen to see whether it is visible outside. To be safe, I suggest holding this screen at the same distance from the window as you plan to have the projection screen. I would not be surprised if this works at night when there is minimal outdoor light to reflect back off of the mirrored window.
