Resources: Acona Biconbi, designed by Bruno Munari

Bruno Munari (1907-1998) was an italian artist and designer who conceived 'Acona Biconbi' as a work of sculpture.

'Acona Biconbi' is also a wonderful toy. You can play with colors and shapes and build beautiful polyhedra. There are unlimited combinations.

You can download and print this template:

We can combine this design with Fred Bassetti's technique of building polyhedra using rubberbands to make more ephemeral structures with reusable modules.

A very simple technique to build complex and colorful polyhedra.

Our first example is an icosahedron:

Duality: icosahedron and dodecahedron are dual polyhedra:

More polyhedra: tetrahedron and octahedron:

Snub cube:

And more:
