Reach out for your 3D goggles because this is a representation of the Cosmos through the eyes of a 5-year old.
The model displays a few objects at various depths and move two of them back and forth on a chart to demonstrate the stereoscopic effect.
Though very simplistic it is an excellent example of anaglyph stereoscopy in action showing you how it’s built.
The farther the red and cyan (turquoise) images are from each other the closer the object appears. Enjoy!
