This Demonstration displays the classification of real Clifford algebras, making the eightfold periodicity manifest by mapping it onto a clock created from the eight trigrams used in the I Ching. We saw that the tridimensional space generate a geometric algebra of dimension (2^3 = 8 = 1 + 3 + 3 + 1) composed of four linear spaces: scalars, vectors, bivectors and pseudo-scalars.

Matrix representation for tridimensional space geometric algebra. In General Math is being discussed at Physics Forums.
