Galaxy Train Through the Stars
A vintage steam locomotive pulls a string of carriages along a curved luminous track that arcs through a deep-space backdrop, its headlamp cutting a warm cone of light through the surrounding nebula glow. Star fields and soft purple and blue cloud bands drift past the windows while distant spiral galaxies rotate slowly in the upper background. The train maintains its forward motion along the track as the cosmic scenery shifts around it, and faint sparks trail from the smokestack before fading into the void. The 3840x2160 loop runs for exactly 19 seconds.
