If the HN commentariat knows of similarly excellent educational work that uses intuitive visual to explain software concepts, please do share.
I have not gone through it yet, but this explanation of how transformers work is in the same class as Ciechanowski's work IMO: https://poloclub.github.io/transformer-explainer/
For JPEG compression: https://parametric.press/issue-01/unraveling-the-jpeg/#param... (anchor doesn't work for me, but it's the one with the caption "Move slider to adjust the amount of subsampling applied." which made me understand the motivation behind using chroma)

For cryptanalysis: https://random.tastemaker.design
For Fourier transforms: https://brianmcfee.net/dstbook-site/content/ch05-fourier/Sim...
