eulerian string circuit

3D Model

The underlying polyhedral shape is made from 18 squares and eight triangles, and hovers in Muir Woods (Northern California). A path visits all the edges once and only once, returning to its original vertex. Colored lines track our progress along this Eulerian circuit! Follow the journey around the hue spectrum with your eyes. Can you see the squares that lie on a cube, and the triangles sitting at the corners of the cube?
