Law of Symetry and Figured-Ground

Adapted from Law of Symetry and Figured-Ground, created by Edmundo Mejía Galindo.

Horizontal lines form a large diagonal field while a central square trades blank and vertically ruled halves across the same boundary. This GIC adaptation highlights symmetry, contrast, and figure-ground reversal.

// ABOUTME: Exchanges horizontal and vertical textures across an implied diagonal square.
// ABOUTME: Demonstrates contrast, symmetry, and figure-ground reversal with line grids.
