I have just finished a very long project with Blender. It´s a short film called 21:00.
It has been made using opensource software. Mainly Blender 2.49 but also PovRay, Gimp, Audacity, VirtualDub, Drumtrack, and some others.
My sister and I put the voice to the characters and some friends lend me some original music for the film: Hitless, Miguel Carro and Roberto Ullán.
Here you can download it from megaupload in Spanish (its about 150Mb):
and with English subtitles:
Hope you like it!!!
