FreeJ is a vision mixer: a digital instrument for realtime video
manipulation used in the fields of dance teather, veejaying, medical
visualisation and TV.

It runs a video engine in which multiple layers can be filtered thru
effect chains and then mixed together with images, movies, live
cameras, particle generators, text scrollers and more. All the
resulting video mix can be shown on multiple and remote screens,
encoded into a movie and streamed live to the internet.

FreeJ can be controlled locally or remotely, also from multiple places
at the same time, using its slick console interface; can be automated
via javascript and operated via MIDI and Joystick.
