Here's a fascinating project by artist and animator Ryan Estrada in which he is attempting to create a full length animated feature film in the space of one month. In Ryan's own words:
"It's always been my dream to make an animated feature, but I've never been able to get the time and resources I need. Well, I'm sick of waiting. This December, I'm sitting down at my desk in the Costa Rican jungle to work. And on January 1st, I'm releasing the finished movie online, free to all".
