3x3x3" Laser Etched in Jewel Cut Optical Crystal

This is an 8 dimensional E8 polytope projected into 3D for visualization. Each shape at the intersection of 6,720 edge lines theoretically represents a fundamental physics particle (e.g. electron, quark, neutrino,...).

This view shows the 8 concentric rings of 30 vertices - the 2D Petrie projection.

The edges have an 8 dimensional length of √2.

There is also a Giclee' print of this projection here.

The photo was taken with the crystal on top of an (optional) multi-color LED light base.
