(This follows on from a video of the ancient relic by Ericlas)
Either FD are messing with us or there's a puzzle encoded in the light of the ancient relic:

The video is a debug cam shot where the camera is inside the relic, and then video enhanced using VLC with hue/brightness all the way down and contrast all the way up.
Does anyone know a quick way to figure out if a video like this has a repeating pattern? Going frame by frame is an exercise in terminal boredom.
My original video has a bit over 9 minutes worth, but I've spent a few days transcribing size changes and only covered around 25 seconds worth of it

It never goes above 12 frame increases/decreases in a row, and occasionally has a few frames in a row where there's no change. It could just be random light to make the thing look cool, but we should check thoroughly.
