hmmm
Chuck-eh, you're seeing this film as the guy upstairs. This animation displayed the downfall of modern isolation. It showed the guy denying contact with a woman, in uncertainty shrugging his shoulders, to go and indulge in self-gratification through music.
I see this animation much more dark. The "transformation" you must be talking about is when the protagonist began listening to music and it colored the surroundings. But then, when the video zoomed out and displayed him in his room, it looked like a television for the stick figures. Making me feel like the Protagonists life is not derrived from the passion of music but how we isolate ourselves from the outside world to dissolve our minds into entertainment. While we sit here on our computers, we're not attending to our true god given desires of love, company, friendship, or anything else. As the outside world is throwing a party and conquering the world...you see.
