Disney Dreams! was a nighttime spectacular at Disneyland Park in Disneyland Paris. It was designed specially for the 20th anniversary of the park. Conceived by World of Color creator Steve Davison, the show features projection mapping onto the park's castle, fireworks, water fountains, fire, music, lasers, searchlights, mist screens and other special effects. Since spring 2011, Dreams began testing with original projector animations but, in late 2011, some scenes that were tested in early 2011 were deleted and others were changed. Using the technique of projection mapping, the castle can be visually transformed in numerous ways such as shrinking, spinning and turrets flipping.
