I recently downloaded Ben Dansie's fantastic "Sintel Lite" model. While great, the model could certainly use several improvements. I made the necessary improvements, but the model was then too "heavy" for my computer to render quickly. And so Sintel Ultralite was born.
The model is rigged, textured, and skinned, with less than 400 verts. A baby Scales is included, but he's not rigged. Perhaps you could use these models to re-film Sintel on a machine from 1990; just make sure your ending makes sense. :)
