This is a concept that has been running around in my head for a while, with a few alterations. In this animation, the fly is trying to go outside and leave this run down house, but is stopped by a forceful wind that knocks him off of the window sill to his death. It's a bit of a somber story where the fly tries to leave the bad conditions he's in to reach something better, but is pushed back by an outside force that he can't control. I created all of the art in Adobe Illustrator and completed the animation in After Effects.
