It's already a grid... you just do not look at it from the right
direction. (and you need cubic brick) Look at it from y.

random orientation might mean using either warp, or / and, some map of
texture/pigment

If it was only for tincture rather than orientation, a direct "cells"
pattern would have been fine. (it's a cubic grid)

If you are ready to replace a plane with textures with multiple objects,
just loop over with a flat box (your idea) with a very very small
perturbation of rotation around its center (in 3D). Just make the box
something like 99% of the grid step, and put an underneath plane for the
dirt. But it will be lost details and might generates moire effects. Of
course each box can have its own texture, including an orientation.

I used to make tiled surface (like laboratory table) with
superelllipsoid (flat, and nearly a box) and two loops.
