Animated horse, made by rotoscoping 19th century photos by Eadweard Muybridge. Artistic license has been used to achieve the cartoony look. Animated by J-E Nyström, User:Janke, released under CC-BY-SA-2.5 (Photo credit: Wikipedia)


Persistence of vision is the property by virtue of which the image formed on the retina of human eye remains for about 1/15th of a second. So, if more than 15 frames are projected per second on screen one after the other in succession, we wont be seeing them as separate but we will be able to enjoy them as continuous action.


See the following video in which Gagnam Style Video is made out of a series of drawings.
