Just a quick hack to experiment what happens if you watch a lot of The Simpsons episodes at the same time. It just took 10 lines of code and a few hours of processing.

About the video:
-Top to bottom: each row shows a season (from season 1 to season 10)
-Left to right: each column shows an episode (from episode 1 to episode 13)

A total of 130 episodes is displayed, framerate is 25fps, thumbnails have been captured at 80x60px
