Show HN: I made a CLI tool that turns pixels into emojis (github.com)

I wonder if you could use this for some kind of "secret" message.

Or perhaps like a parity system like RAR files had back in the day to rebuild any of the other images if one were to get lost.

Somebody is actually working on a language made entirely of emojis called "emojilang, so this could be a way to write a secret message.

You have some conflict markers in your README :)

I feel there's a lost opportunity in not naming this project Emosaic or even Mojaic.

I see that you use euclidean distance of perceptual color and named your color function bad_color_distance. My only input here would be to try something like the CIEDE2000 color difference formula to see if the result can be further improved.

Lol I love this

Or encode any data into emojis: https://github.com/tejado/BaseEmoji

Feels like a good match for rust's 'fearless concurrency'.

With the large number of emojis available, do you still get decent results if you don't use any single emoji twice?

Read the README, and noticed the picture. My first thought was “why don’t they show the result?”.

Then it hit me. Excellent job!

So ... like https://github.com/schani/metapixel or any other photomosaic program, but only one tile per pixel?

*photomosaic is a trademark of Rob Silvers.

I think Floyd-Steinberg could probably allow you to have multiple pixels per emoji.

Hey thanks for this. Even though I don't completely understand it, it's inspired me to find something fun and smallish to create :)

Nice! I made a doom renderer with emojis some time ago, but I decided to keep the emojis bigger, so you could identify them. But I like your approach, will definitely try in my doom renderer too: https://github.com/CrociDB/doomoji
