The design of this fractal is attributed to Dr. Jeannine Mosely. We used approximately 50 000 business card for this Snowflake Sponge. The final model is around 1.50 meters. The folding and the assembly took three weeks involving a dozen of Malagasy maths students. As far as I know, this is the second Mosely Snowflake Sponge Fractal ever built.
