According to Disney this has proven much more popular that their original estimates. Guests use a touch screen PC and can select from a dozen different pallets with many virtual brushes. Each brush paints on the screen something different, from birds to butterflys. The characters are animated on the screen as they are painted. Further there is morphing done.
Bats can morph into vampires for example.
Guests can take home a print from the scene they have created. The intent is to allow the guests to also have an section of the animation. The image was then transferred to a photograph. The play is hosted by Genie from Aladdin which allows a guest to take a high quality photo of themselves. More that one person can participate which brings a social component to this game.
