@MostlyHarmless we found the home of pink floyd? ;-)
@TheTomas @MostlyHarmless It's on the dark side of the moon

Caption for accessibility:

Meme image. The text at the top (black sans-serif text on white background) says "The perfect Christmas light set-up doesn't exi…" (and there is light-grey text saying "@heady_net", presumably a watermark). The picture below it shows an A-frame house in the woods, likely at dusk, surrounded by leafless trees, with lit Christmas lights. The tree has yellow christmas lights around its frame, forming a triangle, as well as one chain of yellow christmas lights to the left from the middle of the roof slope, but on the right, again coming off the middle of the roof slope, is a rainbow formed by several near-parallel chains of Christmas lights. The result is that the house looks like a triangular prism breaking up a beam of light into a rainbow.

@MostlyHarmless what are we looking at? (For those with limited vision)
@tsyum @MostlyHarmless A wooded house lot at dusk. The home is an A-frame style house. The front of the house is decorated with white Christmas lights, making a triangle. A single strand of white lights extends from the left of the scene towards the side of the triangle. Extending from the other side of the triangle are strings of colored lights, which makes the scene resemble a prism and/or the cover of a Pink Floyd album.
It imitates the picture in the cover of Pink Floyd's album The Dark Side Of The Moon
@MostlyHarmless
So does this mean Dark Side of the Moon is a Christmas album?

Sehr großes Like von meinem Sohn (14 Jahre, Pink Floyd Fan).
