The text within the picture reads as follows:

Three levels of simple complexity:

1. Observe the tetrahedron in the bottom left corner.

2. Notice that it is enclosed in a larger tetrahedron. Right beside is
an octahedron, plus there is a tetrahedron in each of the other three corners. Every tetrahedron encloses four half-sized tetrahedrons and an octahedron.

3. Notice that our larger tetrahedron is enclosed by an even larger tetrahedron. This pattern repeats itself getting smaller and getting larger. Part of the complexity can be seen by observing the center octahedron. Notice the red, black and blue hexagonal plates. A white plate has been obscured.
