  A new formulation of Special Relativity is described. It is based on Cellular
Automata theory and on a new theory of inertia called Quantum Inertia. The
universe consists of a huge 3D array of cells given by C(x,y,z), whose numeric
states are updated by every new CA clock period. The numeric state of the cells
depends on the contents of the imediate neigbours and on the mathematical rules
of the cell, with each cell containing the same set of rules. Photon motion on
the CA is represented by information patterns 'shifting' from cell to adjacent
cell at every clock cycle, and this represents the universal speed limit. The
Lorentz Transformations follow directly from this model of light motion. The
concept of mass and inertia is revised to be compatible with the CA model.
