This is one of the first things I did when I started working in this department a few years ago. We had our Parent Conference, and I needed something that fit the theme to play on our back projector screen the entire time. From that, I made a simplified HD version that we still use for some generic events. Just like all the moving background I do, it loops seamlessly.
