Hi, I'm the person behind ShowcaseOS. It's a personal collection of 56 small HTML, CSS and JavaScript projects I've put together for fun over the past few years, one weekend at a time. No frameworks, no build step, just plain files you can open straight in a browser.

Open the Programs window and have a look around. Some of these are silly, some turned out genuinely useful, and a couple I'm still proud of years later. The full source, including this desktop, lives on GitHub if you're curious how any of it works.
