What’s amazing is the innovative technique they used to animate the frames in the film. They programmed an iPad to display slices through each image they wanted to project, then dragged the iPad through the air as it displayed each slice.
Capture that in a dark place using a long exposure, then stitch it all together in stop-motion animated style, and the results are – well, magical.
Here’s the film:
