Why?
my group of friends and I always make a New Year's Eve party in which I am the discjockey. Last year we have a external projector connected to the computer to project videoclips and some videos without sound. To control both the music and video from the same Linux computer with multi-head, I have write this little applicaion that launch the videos in the video projector with or without sound and control the Rhythmbox playing.
How?
Vijockey is writen in pygtk, using the tool Quickly
