The Hasher's Delirium (1910)

Cohl's animation style is rather surreal and also makes good use of the medium. The cartoons are not formally structured, but the images flow easily from one to another as objects melt into other shapes. For example, an elephant turns into a house or a window changes into a man. These films have had an obvious influence on later animated films, such as George Dunning's Yellow Submarine, or the pink elephant sequence in Walt Disney's Dumbo. (filmreference.com: Emile Cohl)
