Commuters and tourists were treated to a very trippy display when a billboard broke down in New York City. And it’s animated, as you can see in the video below.

So what is it, a communication from hyper-dimensional beings? According to a Reddit commenter, the truth is more prosaic — this sequence is played when a technician needs to check if the separate sections of the billboard are properly calibrated. Damn, that is one groovy diagnostic test!

I hope at least one person saw this billboard mid-trip and stared at it for several minutes. Is anyone else seeing this? My God, how much did I take?
