What is site_demo?

3b1b/site_demo is a demo website that turns 3Blue1Brown's popular math videos into written blog posts. Right now, it features a single article on Fourier transforms, but the goal is to eventually convert all of the channel's video content into this written format. It's an experiment in making the visual, animated math explanations that 3Blue1Brown is known for accessible as text you can read at your own pace. Each post offers two reading modes. "Blog mode" keeps things interactive, with short video clips mixed in between the text, closer to the original video experience but in written form. "Print mode" strips things down to something you could print out and read offline, like a chapter from a textbook. You can toggle between these modes with a button at the top of the page, and there's also a theme switcher for dark or sepia backgrounds if you prefer a different look. The audience here is anyone who enjoys 3Blue1Brown's videos, students, teachers, math enthusiasts, or curious learners. A teacher might use the print mode to hand out a lesson in a classroom, while a casual reader might work through the blog version over a weekend. The project is also exploring features beyond plain articles, like embedding quizzes or spaced repetition tools to help readers retain what they learn. All images are shared under a Creative Commons license, meaning others can reuse them for non-commercial purposes with attribution. The project creators are actively seeking feedback on whether people find written versions useful, whether print mode works for their needs, and whether community members would be interested in contributing. It's still a work in progress, and the README doesn't go into detail on the technical setup beyond noting it's a shell-based project.
