A construction site swallowing a star. Six tilted rings of two thousand curved panels cage a multi-layer sun — platinum core, orange halo, wobbling red prominences, angular light rays — while hundreds of drones stream in toward the build frontier and welding sparks flare where each panel closes. The megastructure runs a four-act cycle: the shell spirals into being amid drone traffic and sparks; a beat of stillness as every ring edge ignites cyan; the rings spin up and energy arcs whip between shells at peak brightness; then the panels tumble apart into a dim debris nebula the drones gather back up before the next build. Every panel, drone and spark computes its own state on the GPU, so the whole spectacle is one deterministic node graph driven by a handful of uniforms.
