Light Spot Sundial

Introduces a novel equatorial sundial design that uses a moving light spot, rather than a shadow, to indicate time. The spot is projected onto a central cylinder via concentric rings with slits and holes. The design requires complex mathematical calculations for accurate sizing and component placement, ideal for large installations.
