Long description

The event will be a 3-hour workshop focused on bridging traditional cultural heritage with creative coding. We will explore algorithmic art practices through the lens of ancient Turkish symbols found in Anatolian rugs (kilim).

Event Details:

• Level: Beginner to Intermediate.
• Location: Ozyegin University Campus or a public venue in the city-center
• Date: I am aiming for a date (Saturday) in October 2026 to align with the global PCD window.

I am currently finalizing the venue and will share the specific location and registration details in the coming weeks.
