The "distortions" of the two-point system, in this case, have a nearly fun-house quality.
Yet the space falls logically out of its assumptions.

The regular units of measure are placed around the sides and bottom of the controlling rectangle (marked by the half circles.) Then the perspective lines are drawn to them from the two points on the horizon line.

The grid is symetrial, reflecting the symmetry of the point placement at the corners of the rectangle.

Down the center, the grid units have been colored-in (yellowish) to show the warping effect of the "fish-net" space.
