    We need to invent a device that cancels out the light that comes through a glass window. Like noise canceling headphones but for light

        A lot of folks use blinds which are abject shit for keeping out light, blackout curtains are becoming more common but its still not the norm. Also im pretty sure the OOP is in a Hotel meaning thet prolly cant do any modifications, also if you want to go to Vegas assuming you have a car stay in one of the satellite towns, Primm, Boulder, or a KOA campground.

        Fun fact, most LED displays will only display a very specific wavelength of light for each primary color, if you can isolate the specific values of red, green, and blue, that the sphere uses in the LEDs in its displays, and get tint/filters for those wavelength ranges, you can effectively “tint” the windows where the sphere would be nearly impossible to see, while almost everything else would be fairly clear.

        Almost all other light is broad spectrum, so even a single color item would reflect a much larger range of wavelengths than what the sphere produces, which may make red/green/blue objects less bright through the window, but they will still be observable, while the sphere is basically just black.

        I can guarantee you that there are people researching “variable glass tinting”

          That actually already exists. It’s good tech, but more for out of reach areas or where moving parts would be an issue. For a regular home, curtains work better.
