One challenge we faced was that the original images Sienna exported from Photoshop had black backgrounds. But Chris and Roger helped her figure out a way to export them with transparent backgrounds, which helped Roger add all the minimalist, blobbed out frames of Samus to the animation. 

Then it was time for Chris to add the audio. Initially, she wanted to put in the tritone paradox as an auditory illusion, but she didn’t end up liking how that sounded. So, we decided to toss that idea and keep the focus on the visual illusion. So, Chris added the background music as well as the sound effects for passing through each stage and for descending in the elevator. Then she tweaked the timing of the audio and video to make the final product into a pretty seamless five second loop.
