[jitter] New to Jitter, curious about possibilities

Hi all

I have a few questions about Jitter, and how i could use it creatively when performing music.
Is it for example possible to have a camera pointed at my guitar, and when im for example bending a string, jitter can activate a ringmodulator msp patch?
And for example when djing, can i point a camera to the mixer, and when my crossfader movements exeeds a certain speed threshold, i activate something else?
Im just trying to figure out what Jitter can do for me :)
