Alien Encounter WDI Presentation Art. When new rides are in the early stages of design, pieces of art like this are used to present the ideas to executives to see if it will move to the next stage. Original art is not used for these presentations, but skillfully made copies, such as this one (it might be a digital print out). This image shows the alien monster breaking out of the tube in the center of the attraction and audience members screaming. 24? x 30?.
