I am a retired Chief Technologist in Aerospace and Defense, where I worked supporting IT and Engineering, advanced 3D visualization, simulation, rapid prototyping (3D printing in various materials - during the '90s), etc. I now focus on establishing a framework for (and visualizing) the integration of QM and GR (aka. ToE). The attached pic I created is a Petrie projection of E8 (with algorithmic assignment of fundamental physics particles defining vertex shape, size and color). I use it as a header for my online presence. Interestingly, it was used as the icon for a recent interview with my occasional collaborator, AG Lisi.
