We know we cannot square the circle, but can we box the sphere? Can we go from the green sphere to the magenta cube?
Unfortunately, whatever way we put it just never works.
Description of how this image was created
The golden structure has been built using a single primitive called superellipsoid. We see 225 such objects with different parameter values to create many interesting shapes. The arrangement have the look of Escher-like designs where the in-between reveals something. In this case, we see an attempt to square the circle.
The red "sphere" has been created thanks to the internal simplex elements used by CSG modeling. It is contrasting with the cyan "cube" which is yet another unsuccessful attempt to box the sphere.
The topic has been exploited in some other ways. We have of course the opposition of the sphere versus the cube, but we also have a few pairs of complementary colors such as gold on blueish background. The primary and secondary colors (namely red, yellow, green, cyan, blue and magenta) are ordered counterclockwise and suggest the chromatic hexagon.
