I made a CLI tool that turns pixels into emojis
Takes a folder of images (as a palette), and an image, and figures out how to tile the palette to resemble the image! - ahhhh6980/Mosaic
I made a CLI tool that turns pixels into emojis launched on March 20, 2022 with 105 votes, #336 of 3,153 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 4 years on.
In plain words
This is a command-line tool that converts pixel images into emoji representations. It's designed for developers and anyone interested in ASCII art alternatives. The tool takes image files and translates their visual content into corresponding emojis, creating a text-based version suitable for terminals or text documents. It launched in March 2022 and is available on GitHub.

Image Object Removal APIDec 2025 · replicate.com · ▲117This demo allows you to recreate images using emojis. You can provide images or emojis to paint with, and it will attempt to recreate images using emojis. Much of the code is adopted from the Paint Transformer (https://arxiv.org/abs/2108.03798) paper. In this code base, I treat emojis like “brushes”, and use a Gumbel Softmax-based lookup to choose an emoji to paste to the canvas during training (similar to how attention uses a softmax to select keys during training).

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hi HN! I made many small web games in the past with Unity or Phaser. But this time I wanted to make something completely on my own. So I coded a basic game framework in plain JavaScript, and used it to make Almost Pong. This was a really fun project that taught me a lot about JavaScript, and I plan to make more minimalist games with this framework. Interesting fact: Almost Pong doesn't load any assets, all sprites and sounds are generated with code. Happy to answer questions, and please let me know if you have any feedback on the game. Thanks!
