zeroglab nanofestival is a miniature portable festival of very short (10 second) digiVids. They use a Creative Commons license to let the whole festival be taken up for free.
Here is how they describe their project:
ZEROGLAB NANOFESTIVAL is a parasite, portable, adoptable, resizable, open source, international art festival for extreme short (10 sec.!) web movies and software art.
Nanofestival as an event is also establishing a new model for cultural engineering.
Not only the individual works that are open source, but the whole festival can be ‘picked, taken and presented’ for free, and by anyone on a single cd-rom.
