Squigglevision is the method of computer animation in which the outlines of shapes are made to wiggle and undulate. Tom Snyder invented the technique, which his animation production company subsequently popularized in several successful animated series, most notably "Dr. Katz."
In order to create the line oscillation effects that characterize Squigglevision, animators loop five slightly different drawings in a sequence called a "flick." The animators then operate software from Avid Technology to merge the flicks into the scene, and synchronize them with the soundtrack.
Compared to traditional animation, Squigglevision is relatively fast and easy to produce. The non-stop motion of outlines creates an "economy of motion," which reduces the need for more complex animations in order to make a scene feel dynamic. According to Snyder, "there are almost no disadvantages ... It costs just as much to do a helicopter scene as it does to do a living room scene." Conservely, critics have described it as distracting and annoying, and some even claim Squigglevision gives them headaches. "Home Movies" used Squigglevision in its first season but dropped it from later seasons due to negative feedback from viewers.
