I’m only seeing an image, with no explanation, and it took me a while to realise what it was showing; so, in case anyone else is puzzled by it, each image is the sum of the previous one with a new factor (indicated by the wheels upon wheels”).

I think that the reconstruction of Homer Simpson’s face (which I think I originally saw thanks to OP ColinWright!) may be a more convincing demonstration of the power of Fourier transforms:  . There’s a Nautilus article about it, too: http://nautil.us/blog/the-math-trick-behind-mp3s-jpegs-and-h… (EDIT: and an HN post discussing that: https://news.ycombinator.com/item?id=6683866 ).
