This demo employs a 3D interface to reveal the paths taken in a 3D Random Walk. Each time green flag is pressed, a new walk is generated. Up/Down Right/Left arrows and a/z keys rotate the object along the x,y,z axis.
The 3D interface is a based on a projection algorithm I developed some years ago to make Geometer's Sketchpad display 3D curves. I learned a tremendous amount from @Mr_Pyro_ 3D Wireframe Engine project about optimizing rendering and keyboard effects. Much much thanks.
