    TLDR: Click the link to see some cool visualizations, refresh a few times for random examples, and try editing some of the code yourself. This is a small weekend project of mine inspired by shadertoy.com It's a static single-page site hosted on GitHub pages so the website design is pretty barebones. I'm not a web developer so I mainly wanted to create a Cool Thing with my free time and not have to learn tons of front-end to do it. I'd love to hear what people think about it and please post or send me any shaders you make! You can use the link button in the bottom right to share. I hope that…

    There are lots of glassmorphism generators out there, but I wanted to push the effect further! This project is the result of months of experimenting with CSS property layering and battling browser quirks. Cross-browser compatibility is actually the reason I rely on ::before and ::after pseudo-elements to build up the effect. Move the color/opacity to the main element, and you’ll get weird color bleed on the corners in Chrome. Move the texture, and it muddles the bevel’s specular highlight. Move the bevel, and it gets blurred out by the backdrop-filter. And so on! Layers include: *…

    I'm working on a pure js webgl image editor with effects, filters, crop & perspective correction, etc. My goal is to give the community an opensource solution as unfortunately most comparable apps are closed sources. https://mini2-photo-editor.netlify.app to try it out (https://github.com/xdadda/mini-photo-editor)

    Last summer there was an Ask HN[1] about a Nature article that said bluring the blue and green color channels on screen may be good against early myopia development. The OP wanted such software and there was none available. So I quit my job and implemented this software, did a short video with a 3D artist about it. Turns out marketing is expensive, so I made an open source browser extension version too. How it works? There is a small neural network on the retina that tries to detect if the eye is far-sighted(most people are born far-sighted), and it is producing dopamine to slow or increase…
