first ever 3D stereoscopic stop motion and CGI short in the history of film. The first all stop-motion 3D feature is Coraline (2009), based on Neil Gaiman's best-selling novel and directed by Henry Selick. Another recent example is the Nintendo 3DS video software which comes with the option for Stop Motion videos. This has been released December 8, 2011 as a 3DS system update. Also, the film ParaNorman is in 3D stop motion. Go motion Another more complicated variation on stop motion is go motion, co-developed by Phil Tippett and first used on the films The Empire Strikes Back (1980), Dragonslayer (1981), and the RoboCop films. Go motion involved programming a computer to move parts of a model slightly during each exposure of each frame of film, combined with traditional hand manipulation of the model in between frames, to produce a more realistic motion blurring effect. Tippett also used the process extensively in his 1984 short film Prehistoric Beast, a 10 minutes long sequence depicting a herbivorous dinosaur (Monoclonius), being chased by a carnivorous one (Tyrannosaurus). With new footage Prehistoric Beast became Dinosaur! in 1985, a full-length dinosaurs documentary hosted by Christopher Reeve. Those Phil Tippett's go motion tests acted as motion models for his first photo-realistic use of computers to depict dinosaurs in Jurassic Park in 1993. A low-tech, manual version of this blurring technique was originally pioneered by Władysław Starewicz in the silent era, and was used in his feature film The Tale of the Fox (1931). Comparison to computer-generated imagery Reasons for using stop motion instead of the more advanced computer-generated imagery (CGI) include the low entry price and the appeal of its distinct look. It is now mostly used in children's programming, in commercials and some comic shows such as Robot Chicken. Another merit of stop motion is that it accurately displays real-life textures, while CGI texturing is more artificial and not quite as close to realism. This is appreciated by a number of animation directors, such as Tim Burton, Henry Selick, Wes Anderson, and Travis Knight. Stop motion in other media Many young people begin their experiments in movie making with stop motion, thanks to the ease of modern stop-motion software and online video publishing. Many new stop-motion shorts use clay animation into a new form. Singer-songwriter Oren Lavie's music video for the song Her Morning Elegance was posted on YouTube on January 19, 2009.
