Stop motion: Stop motion (hyphenated stop-motion when used as an adjective) is an animation technique that physically manipulates an object so that it appears to move on its own.  The object is moved in small increments between individually photographed frames, creating the illusion of movement when the series of frames is played as a fast sequence.  Dolls with movable joints or clay figures are often used in stop motion for their ease of repositioning.  Stop motion animation using plasticine is called clay animation or "clay-mation".  Not all stop motion requires figures or models; many stop motion films can involve using humans, household appliances and other things for comedic effect.  Stop motion can also use sequential drawing in a similar manner to traditional animation, such as a flip book.  Stop motion using humans is sometimes referred to as pixilation or pixilate animation.
