Ignite geometric wonder with the Pyro-Balls featuring Andrea
Hawksley's 6-Card Ball Design by Sly Designs
Assemble six precision, pre-cut playing cards into a compact,
interlocking spherical polyhedron that conceals a stunning secret: an
elegant dodecahedron clearly visible at its core.
Created by mathematical artist Andrea Hawksley, this clever design
uses just six cards—each ingeniously representing two faces of the
underlying regular dodecahedron—resulting in a structure with
pyritohedral symmetry (a fascinating subgroup of icosahedral
symmetry, blending full dodecahedral beauty with pyrite-like
distortions). The result is a mesmerizing, soccer-ball-like orb that's
both a visual delight and a subtle mathematical puzzle.
No glue, no tape—just slotting and interlocking folds that click
satisfyingly into place, revealing intricate patterns and a harmonious,
display-worthy sculpture from every angle.
