This was our group's submission for the 2004 Cinemasports 11-hr film festival in San Francisco.
Each team was to make a short film that contained the following elements, a list of which were handed out at 9am:
1. a character discovers something about himself
2. flower petals falling
3. mention of a favorite pet
4. something peculiar seen in a mirror
All films screened at 8pm. I'm not sure anyone knew what to make of ours, nestled between 3-6 minute comedies and dramas.
The internet archive has a 1-minute documentary on that year's festival:
