As I continue my experiments with GeoGebra 3D, I thought about that lace pattern. Rather than reinventing them, I borrowed from http://paulbourke.net/geometry/baseball/, and used them in this graphic. Nothing fancy. Just getting a handle on GeoGebra 3D features.
One of the features I am having issues with is getting a 3D version (the kind you have to view with special glasses) to save and embed successfully. Wish me luck!
