Project Year: 2026

This project shows how a mathematical rule can generate a physical drawing. By arranging whole numbers along a spiral and marking the primes, it makes numerical relationships visible as curved patterns. Students can explore how mapping numbers to positions changes what they see, while the continuous drawing path encourages them to consider how computational rules translate into practical pen movements.
