That is awesome. Chaos on one side, order on the other, in the middle a sierpinskitriangle. Btw, there are only 255 rules, -89 is equivalent to 167

Nice! You can also use & instead of | for a slightly different style. i&i/t is also good

shouldn't it have a triangular base?

That would be a tetrahedron. Pyramids usually have a square base.
