| Besides the 1996 outline-map version, this is one
of ten larger, printable versions, with varying resolution and content. The
tabs enable them to be folded and pasted into pseudo-globe octahedrons. (Furuti's truncated octahedron variants
make a closer approximation of a globe, but their cut-to-fold layout is not
a Butterfly Map: instead, a disparate pattern, not included in this gallery.) * © 2001,2003 Carlos A. Furuti; first online date 2003-02, per Internet Archive. |
