This 30–45 minute lecture-performance introduces an exploratory, research-based video game environment that brings together music, architecture, and speculative worldbuilding across the Swahili Seas, connecting East Africa, the Gulf, and South Asia. Through gameplay excerpts, sound, and visual material, the presentation frames the work conceptually and contextually, situating worldbuilding as a method for sensing historical memory, oceanic exchange, and alternative technological imaginaries.
