It seems that Lorentz invariance might be the result of the light speed limit of forces/information transfer *within* particles, and observers made from multiple particles. Why did nobody tell me? Is this a thing? Can someone point me to work on this?
Yes, if you want to construct a glider that preserves momentum without anisotropy, it will have to be distributed over many adjacent locations. (The number of directions a glider can take on a [stochastic] lattice depends on the number of cells it occupies simultaneously.)

The alternative is that you have to compute the momentum over a large amount of preceding states (that is what Wolfram has sometimes been doing), but it does not strike me as elegant. I like to think of the universe transition function as correlating adjacent states only.
