Maybe I'm crazy (or it is an accidental illusion most likely) but when scrolling it seems like the content of the image below the 'flatpack cad' heading almost moves (i know it doesn't actually). I'm curious what kind of illusion is causing this or if it has something to do with vsync in the browser?

I think I can see what you mean when I scroll fast enough. It looks like horizontal movement either to the left or right depending if you're scrolling up or down.

Closest thing I could find is something called the "serpentine illusion". https://www.frontiersin.org/journals/neuroscience/articles/1...
