Twenty-three interactive explorations of Inselberg's geometric framework, from the duality that makes it all work to exceptional root systems and the connections that emerged along the way.
A 5D point can't be pictured directly. Draw five parallel axes and connect the values as a polyline, and the point becomes visible. Correlations appear as crossing patterns; clusters as bundles; hyperplanes as structured signatures.
Alfred Inselberg developed the mathematical foundations over decades. These explorations make the geometry interactive: drag points, brush axes, rotate polytopes.
The vocabulary
Six colors recur across the series, each tied to a geometric role: blue is always a polyline, red is always a convergence or crossing.
polyline
The image of a point, a broken line that zigzags across every axis.
