O.k. These aren't great, but guaranteed originals.
My neighbour spent a summer without curtains or blinds
Used to get a nightly show. Generally it would be about the same time each night. Problem was, my wife was always in the room, so could never get a good recording (I bought a video camera especially).
Managed to catch her on a couple of occasions when wife was away.
She must of spotted me though because a couple of days later, she suddenly started drawing her curtains
