Hey, author here. I'm really glad to see this getting some traction on HN, it is one of those projects that really brings me joy. It is inspired by a project that I saw on HN a while ago. I wasn't able to find it again, so I made my own version. I swear, only after finishing Pulsar I managed to find https://tixy.land/ again. As a bonus, I wanted to run these animations on my DIY LED frame. Check out the video: https://github.com/Stanko/pulsar/tree/dev#led-retro-frame Here are a few technical details: It is built in TypeScript and open source. User code is executed in a web worker to minimize the risk of malicious use (tbh I'm proud of the solution, and I find it quite nifty). Initially, I used to render everything as an SVG, but in order to create GIFs for the LED frame, I switched to canvas. Not to mention that SVG gave me a few headache

s which I'll cover in a blog post (if I ever write one). The syntax highlighter is a trick I found on Stack Overflow. The textarea is transparent, and as you type in it, I take the code, highlight and copy it into a div which overlays the textarea. It was really fun to build and I hope you had some fun playing with it. I made it around last new year's eve, so here is a simple animation of a Christmas tree: https://muffinman.io/pulsar/?grid=classic&animate=both&code=...

Hey everyone, here is a small project that truly brings me joy. It allows you to create and share animations using code. Instead of me explaining, please try playing with it. If it doesn't click right away, consider going through a tutorial. Pulsar is inspired by something I came across on HN a while ago. Unable to find it again, I decided to create my own version. I swear, only after finishing Pulsar I managed to find it again [1]. As a bonus, I wanted to run these animations on my DIY LED frame. Check out the video: https://github.com/Stanko/pulsar/tree/dev#led-retro-frame I intended to write a blog post before sharing it on HN, but that is taking forever. So, I'll just give you a few technical details: It is built in TypeScript and is open source. User code is executed in a web worker to minimize the risk of malicious use. I'm proud of

SVG gave me a few headaches which I'll cover in a blog post (if I ever write one). The syntax highlighter is a trick I found on Stack Overflow. The textarea is transparent, and as you type in it, the code is highlighted and placed into a div which lays on top of the textarea. So, that is Pulsar. I hope it will be as fun for you as it is for me. Let me know what you think. I prepared a simple animation of a Christmas tree for the holidays. It is a bit late, but here it is anyway :) https://muffinman.io/pulsar/?grid=classic&animate=both&code=... [1] https://tixy.land/
