Pixar's production logo—that animation sequence that pops up before a Pixar movie—is as iconic as they come. Who can't help but smile when they see cute little Luxo Jr. squash the I in Pixar and turn its bulb towards you. But the Pixar logo animation wasn't always so adorable, a few of Pixar's early shorts had much plainer sequences. Jay Orca combined a lot of them into this wonderful 3-minute video showing the history of Pixar's logo.
