Here is my first prototype sconce light that demonstrates how to create a double spiral by applying a light projection from the top of a loxodrome onto a plane. This type of projection is called a stereographic projection. This prototype is 4 inches in diameter and uses a bright warm LED for a nice looking night light. This is still a work in progress. More to come soon...

There are many ways to cover geodesic domes with a network of knots.
