Welcome to /m/!
A modern take on 4chan's /f/ board.
Unfortunately there isn't quite a good way to allow interactive content (yet). but /m/ does do looping video files.
Which allows for fun loops like the all time classic "lolicatgirls" to see new life (see this thread)
If you'd like to get started with creating your own loops, but don't have money for Editors like Adobe Premiere, there are tools like Shotcut that are just as good.
