This is an experiment to play with a technique for making a blurred background based off a video.
I made a collection of low resolution thumbnails with ffmpeg. They are expanded to cover the full frame of the browser window, blurred, and darked.
Every five seconds the page checks the timestamp of the video and loads a corresponding thumbnail which is transitioned to by changing opacities between divs that contain the thumbnails.
