This is a 1965 Oscar-nominated experimental short film called Time Piece. This was written, produced, directed, and starring a young man by the name of Jim Henson. Yes, you hear me right, THE Jim Henson. Who knew the guy can make such a cool thing like this without a Muppet in sight? Fellow Muppeteer Frank Oz (Miss Piggy, Fozzie Bear, and Yoda in the Star Wars films) also later went on to direct comedies such as Dirty Rotten Scoundrels, Bowfinger, and more recently Death at a Funeral.
