any scientist would go “oh hey thats Fibonacci!”

Agreed, except in my crunchy post-pedal glitter punk opera they would say, "oh hey that's the numbers my screensaver uses!"

Although seriously, what would dictate the "start" of the disk - the top, left, foremost block? I think we can assume they would try to read the data contiguously, but that's about it. I guess you could have some kind of visual indicator, like it's in a different colour...

Interesting problem!
