Pencil Test is a 1988 short film created by Apple Inc.'s Advanced Technology Graphics Group to showcase the animation capabilities of Apple's Macintosh II computer line.
A pencil tool escapes from the Macintosh interface when no one can see it, as it wants to take a closer look to a wooden pencil on a desk. Afterwards, it attempts to get back onto the screen but the computer has been turned off by an unseen human presence. The pencil tool finally manages to turn on the computer but when it tries to return to the software programme is no longer possible and ends up smacking onto the screen. After the credits, you can hear a sound of the screen shattering.
