YouTuber Craig J. Clark nailed this one. From Coulton's 2011 album “Artificial Heart.”
This music video is my own reimagining of the song "Still Alive" by Jonathan Coulton (from his 2011 album, "Artificial Heart") using public domain films found on Archive.org. I wanted to avoid making any overt references to the game Portal, or to recreate the video game for this music video (since there are already plenty of those videos to be found online, anyway).
