What is this? Super Bowl LII at roughly 1/2561x speed (0.015 fps; 85.45 seconds per frame.)
What are the things at the bottom and top? The text in the lower left displays the index of the currently-displayed frame, and the time at which it appeared in the original Super Bowl broadcast. The bar at the top is a countdown to the next frame. You can hide all of this by clicking anywhere on the image.
When will it end? At 6:30pm ET on February 3rd, 2019 - just as Super Bowl LIII starts.
