I thought about making the box that the alternate Earthers use to copy the shape of people from our side.
Does anyone recognise the box with the little window used in this prop?
It looks like the window is original and it might have writing of some kind behind it. Also the "lid" looks to be glued on. The box on the left seems a bit newer and cleaner - no glue. Or maybe the one on the right was painted and the paint is coming off its edges as it appears darker.
The switch cover is available easily enough and the cable might be a retractable USB cable or similar. It was months ago that I made this capture and can't recall what the switch underneath was like. Normally these covers are used to protect keyed camlocks and keyswitches from the effects of weather.
I'll have to try to get some more screen captures if I can remember which episode it was.
