Make a 10-second cinematic film in Blender: a black steam locomotive plowing through deep snow in a pine forest at golden hour, snow spraying off its plow, thick steam clouds rolling back over the train, warm low sun through the trees. Model the locomotive, tender and two coaches, the track, the trees and the terrain yourself in Blender, animate the train and the camera, and render 1280x720 at 24 fps with Cycles. The locomotive must be big in frame from frame 0. Save film.mp4, a still of the best frame and the .blend. Make index.html that plays film.mp4 muted, autoplay and looped, full width. It should look like a movie shot the moment it loads.
