One of the common uses for a Raspberry Pi is a low-cost information display, powering something like a magic mirror or an animated GIF photo frame. FullPageOS is a Raspberry Pi operating system that makes that process a little simpler.
FullPageOS is set up to boot into a full-screen Chromium window on boot. This means if you’re using your Pi to power an information display, you won’t need to go through the process of disabling screen savers, editing display size, and forcing full-screen mode on your own. All you need to do is install FullPageOS on an SD card, then edit a TXT file to include your Wi-Fi network info and the URL you want it to load up. This is a pretty niche little distribution for the Pi, but it should make those dashboards and other HUDs much quicker to set up.
