Note block, paper and plastic. Contributed by Glen Whitney.
[12 F, 30 E, 20 V] This item departs from the norms of the show: it is not an art piece and it was not specifically produced to be a part of Polyplane. Rather, this consumer product shows the degree to which polyhedral forms have seeped into popular culture, in that something as commonplace as sticky note pads should be produced in the form of one of the five Platonic solids, discovered and revered by the ancient Greek mathematical community.
The other four Platonic solids are also represented in Polyplane: regular tetrahedron, cube, octahedron, and icosahedron. Together with this form, the regular dodecahedron, they exhaust the possibilities for creating a three-dimensional form with identical regular polygon faces that meet only at their edges and with identical angles at all such meetings.
