I helped my son and his friend make their first stop-action video, Hermione's Family Jewel. The 2:00 minutes movie (2:00 minutes so they can enter it in the Fargo Film Festival's Two Minute Movie contest) is an homage to Harry Potter, Star Wars, Indiana Jones, with a really quick scream-out to The Simpsons. The boys pulled in all the allusions, I just helped them get it down to 2:00 minutes.
I discovered The Free Sound Project while helping the boys: a creative commons sound fx database. Sweet and impressive.
