Center This Div
Nobody can center a div to 0.0001px. 3,000+ tried.
What it does
The most over-engineered centering challenge on the internet. JARVIS-style HUD. Sub-pixel precision. Global leaderboard. 0 successes. Ever. Drag a div to the center of the screen. Sounds easy. The success threshold is 0.0001px, about 5,000x smaller than a single Retina pixel. A real-time HUD tracks your deviation to 6 decimal places. When you fail, you get an Earth Scale comparison showing your miss as real-world distance. 3,000+ attempts from 14+ countries. Zero successes. Fully open source.

I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

I wanted Apple Vision Pros, but I don’t have $3,500 in my back pocket. So I made Apple Vision Pros at home. This was just a fun little project I made. Currently, the website doesn't work on screens less than 1200x728 (Sorry mobile users!) It also might struggle on lower end devices. For best results, have a webcam pointing right at you. I tested my website with a MacBook camera. Any comments, questions, or suggestions are greatly appreciated! blog: https://blog.andykhau.com/blog/eyesite check it out: https://eyesite.andykhau.com/ github:…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
