Creating ''animation loops'' or ''animation cycles'' is a labor-saving technique for animating repetitive motions, such as a character walking or a breeze blowing through the trees. In the case of walking, the character is animated taking a step with its right foot, then a step with its left foot. The loop is created so that, when the sequence repeats, the motion is seamless. In general, they are used only sparingly by productions with moderate or high budgets.

[[Ryan Larkin]]'s 1969 [[Academy Award for Animated Short Film|Academy Award]]-nominated [[National Film Board of Canada]] short ''Walking'' makes creative use of loops. In addition, a promotional music video from [[Cartoon Network]]'s Groovies featuring the [[Soul Coughing]] song "Circles" poked fun at animation loops as they are often seen in ''[[The Flintstones]]'', in which Fred and Barney (along with various Hanna-Barbera characters that aired on Cartoon Network), supposedly walking in a house, wonder why they keep passing the same table and vase over and over again.
