Hey guys, this year I’m going to teach a group of students in my university and we are going to join a short animation festival. Is there any good festivals you can recommend with a category for students? And it would be really good if these festivals are about 6 months later, because nobody knows anything about blender right know

edit: You could also purchase the special issue (Sonderheft/Sonderausgabe) of german CG-magazine “Digital Producion” called “Start-Up”.
It`s from march 2009, but still available through their online-shop for 5€ (+7%MwSt. + 5€ international shipping).
The point is, on pages 63-65 of said issue, you`ll find an extensive list of international shortfilm- and animation-festivals from A to Z.
Anyway, here`s a link trough which it can be purchased.
Thanks man! This is some good information. And here is another one from me which I found very useful: cartoonbrew
