There is a song that uses the concept of Tetris, and the folk tune used in the game, in order to tell the "complete history in the soviet union". Besides being "meta", it's also clever and kinda catchy.
This is a fantastic piece of work, and I should point out that the film is potentially even better than the song, which is itself brilliant. I imagine the people who put it together have gone on to extremely successful careers if they didn't have them already, winning for it as they did multiple international awards.
