Space-Filling/Mind-Filling is an artwork designed by David K Butler, with many students and staff of the University of Adelaide assisting in its construction. The artwork is built from shapes called Silver Rhombic Dodecahedra, which have been made from origami units folded from A4 paper according to a design by American origamist Nick Robinson. You can see how to fold the rhombic units in this YouTube video.
Special thanks go to Nicholas Crouch, Daniel Kon and Carolyn Haese for especial effort in construction.
Currently the artwork is on Level 3 of the Barr-Smith South building on the North Terrace Campus of the University of Adelaide, just next to the Polygon lecture theatre. It is still under construction across 2016 and 2017, and to join in, please visit the Maths Learning Centre on Level 3 of Hub Central to learn how to build the dodecahedra.
