10 PRINT

Based on Fabian's 10 PRINT sketch, this drawing makes a 20 by 20 field of diagonal strokes. Nested repeat blocks visit each 5-pixel cell, while a seeded random choice selects the diagonal direction. Compare the regular grid with the unpredictable path.

// ABOUTME: Draws a randomized field of diagonal grid marks.
// ABOUTME: Ports Fabian's 10 PRINT sketch to the GIC canvas.
