drawing lines in jitter

I would like to draw lines in Jitter. I attached a short video from a workshop in modul8. You should watch from minute 1:07.

you should be able to create lines by telling jitter the point A and point B of a specific line and afterward B of this line would become point A for a whole new line and so on. maybe log the moves you make and generate them later on. maybe change the color (gradient style or not), let it shake a bit according to..let's say, sound..

I know Processing and vvvv can do it, even Modul8 has this integrated so why not jitter.

I bet jit.gl.sketch is the secret but i dont seem to figure it out.

Thank you for any help on this matter!
