Sometimes, you just want to be able to loop some videos with no muss and no fuss. Enter German artist Julius Schmiedel who has developed a downloadable OS image, called MP4Museum, based on Raspbian Lite and OMXPlayer which reads MP4 files from a USB drive and just plays them alphabetically, on a loop. And, oh yes, it’s read-only which means you can just yank the power from it without causing OS corruption! Get the OS here. Thanks to Adafruit for spotting this one!
