Hi
I am also searching for this
freeframe in processing would indeed be fantastic
but there seem to be no information about it
and i really wonder why

Well, until today, I ignored what FreeFrame is. Apparently, it is a native application (written perhaps in C or C++). A quick search of freeframe java doesn't show much hits. So I guess nobody wrote a Java wrapper for it. It can explain the lack of bridge with Processing...
