Ogdoad

A game of 8 coloured rainbows, mystical numbers, and the things you see when you close your eyes

Inspired by the notion of a game-playable Zener card set, Ogoad is an experimental pack of cards in 8 colours (sampled from Newton's rainbow) and featuring 8 shapes featuring the Neoplatonic mysteries (monad, dyad, triad, and tetrad) and the form constants of hallucination (Tunnel, Spiral. Web and Honeycomb). The four Neoplatonic forms can all be promoted to the aligning form constants, making for a set of cards in a partially directed acyclic graph relation.
Playing a game of switch with the set is unforgettable.The Ogdoad is an 8-suit, 8 cards per suit, pack. Any traditional game can be adapted to it.
The suits are based on the hues of an 8-colour rainbow: Red, Orange, Yellow, Green, Cyan, Blue, Indigo, and Violet.
In each suit there is a sequence of 8 symbols, made up of two corresponding sub-sequences: 1-4 shown as Pythagorean Sacred Shapes & 5- 8 shown as Klüver's Form Constants. Cards follow by a match on colour or symbol; by raising from shapes to constants, or by blending primaries to secondaries.
