Hidden Room

Adapted from Hidden Room, created by Edmundo Mejía Galindo.

A regular field of horizontal lines stops around a centered square. The interruption turns empty space into a room-like figure.

// ABOUTME: Draws a field of horizontal lines interrupted by a centered white room.
// ABOUTME: Demonstrates how regular repetition and negative space define a hidden shape.
