Here's a website that I check constantly.
It features amazing short films sorted by genre, topic and style. Whatever film you're in the mood for, they've got it. And, it's short!
I really like the idea of short films; you have to make your point in a short period of time. It should convey emotion, be thought-provoking, or funny within a couple minutes. I'm trying to accomplish all of that, WITHOUT dialogue. ha. Good luck to me. :)
