Cat Motif Carved Sphere Tessellation Art

This is a carved wooden ball, 8cm in diameter (3.2"), carved by tessellation artist Doctor David, the first webmaster of this website. It shows his cats, neatly and symmetrically fit together like a 3D jigsaw puzzle pattern on this sphere.

See how to make a tessellation art sphere like this in the 'Do It Yourself' section about "solid stuff".
