## On the Subject of Facets & Logic

Liberal status: Destroyed

- On the module is a floating polyhedron with a button on each face.
- Each button is labelled with the non-overlapping parts of two overlaid symbols denoting different truth values.
- The primary value depends on the properties of the polyhedron.

Primary properties are sorted into four groups.

Inversions of symbols denote negations of the primary value. - The secondary value depends on the primary values of the buttons on adjacent faces.

- The primary value depends on the properties of the polyhedron.
- Press all buttons whose secondary values are true.

If there are no such buttons, press all buttons whose primary values are true instead. - Select the ring from a particular direction to roll the polyhedron in that direction.
