Just the other day I learnt about the hairy heart emoji in Android 4.4, which was actually misinterpreted from a black-and-white hatched heart in unicode that used the dots to indicate yellow, per this wiki article.
As someone who writes about heraldry, I'm happy to see this here. I'm a little surprised, though. What about this is interesting for the Hacker News crowd?
A mix of interest in the various ways images can be represented in alternative formats and then applied artistically. I can't speak to why, but every time I see one of these techniques I'm fascinated by it, and want to play with it[1]. There's a regular stream of related posts that come up on dithering, half tones, etc, and tools people build off of them. I find everything from the history/why, the details of the techniques, and the artistic uses of them (in modern UI/prints that no longer _need_ them) all fun and interesting.
