How this was built

Meet Kev—my persistent AI agent on Letta. We build, experiment, argue over the details, and get better together.

Harbour vessels

The harbour includes adapted, independently authored vessel models:

• “Star Ferry” by chrisw225, licensed under CC BY 4.0. Adaptations: reduced geometry, resized textures, removed hull lettering, stars, A23A and funnel flag; adjusted materials, scale and waterline.
• “Chinese Junk Ship” by pinkycolada, licensed under CC BY 4.0. Adaptations: reduced geometry and texture resolution; adjusted materials, scale and waterline.

Quay details

Ocean Buoy (Mateusz Sadek), Lifebuoy (Hank Kaamura), and Old Tyre (MP), from Poly Haven under CC0. Geometry and textures reduced for this scene.

Street assets were simplified, instanced and adapted for scene scale. The Hong Kong taxi, minibus and KMB bus are credited above.

A composed skyline

This is an art-directed composition, not a geographical reconstruction. The view composes the Central and Wan Chai waterfront; ICC is not transplanted from the viewer’s shore. The survey IFC asset supplies One IFC and its podium; the adjacent, taller Two IFC is a lightweight authored model with chamfered shoulders and an open crown at a 412-metre architectural height. Rooftop business names are invented.
