KFKF - Kids For Kids Festival - a film festival for kids with films made by kids.

"The first experimental Kids For Kids Festival was created in 2001. It was held during the 3rd World Summit. The results were encouraging and CIFEJ was asked to implement the project and manage the annual international event. Young filmmakers, aged 6 to 16, from all over the world, were invited to submit their films. The second edition of the Kids For Kids Festival took place in Athens, in June 2004 and was a huge success. A special Sports category was added that year to celebrate the Olympics. Over the next three years, the festival was held in twice Naples, Italy (2005 and 2007) and Nicosia, Cyprus (2006). Again these wonderful events brought together many young people from all over the world and demonstrated the talents and potential of young filmmakers." from About KFKFilm Festival
