I recently completed these illustrations for a blogpost written by Sean Gryb about a talk given by Derek Wise at the 2013 International Loop Quantum Gravity Seminar entitled “Holographic Special Relativity: Observer Space from Conformal Geometry“.
It was a real challenge to try to render the geometrical model that Sean is describing. It was interesting that we were able to compress dimensions visually and use projections and relatively simple forms to illustrate some basic qualities of this model, some components of which are 4 dimensional objects in 5 dimensional space.
