16-Tesseracts.mov
Here are 16 differently colored tesseracts (4D cubes) arranged in a 2x2x2x2 pattern. Imagine 8 cubes stacked so there are two in any direction and you'll get the idea. The axis are colored: red is x, green is y, blue is z, and white is w. So, the light yellow block is +x, +y, -z, +w.
Also - a special thanks to SharkRetriever for the inspiration to create this. His video response shows the images that inspired this model.
