Snapchatter CyreneQ assembled 20 users for a Snapchat mashup. Each artist took a turn drawing over the another artist's snap, keeping at least 25% of the previous artwork the same. Think of it like a Snapchat version of Telephone.
The mashup resulted in some wildly imaginative drawings of Harry Potter, Pikachu, dragons, Harry Styles, Keyboard Cat, Patrick Star, a corgi, Captain Jack Sparrow, Marlin and Dori, Hulk Hogan and a bunch of original cartoon characters.
