This may or may not be what your looking for but it is the first thing that comes to mind from the description. Uses LCD, but also possible in Jitter.

Sounds like a fun piece!

Thanks guys, those both look great! But what I was hoping for was something that would constantly draw and erase lines over the duration of the piece, I should have made that clearer, my bad! It's been suggested to me that jit.gl.sketch could probably do what I'm after but I've not been able to get it to work so far. Thanks for the help and advice!

I just took what Dobrian did and added a metro so that it constantly redraws... the speed of the metro will control how fast it redraws.

you could use jit.gl.sketch to do something similar, but i don't see any advantages to doing it that way.

Thanks everyone! I've managed to modify Nate's suggestion by adding variable number control to both of the random objects in the patch - I've also got it so that when either of the numbers change, it rebangs for a fresh image. I'm controlling the numbers through the arudinome I built which has tilt control, so that left/right increases and decreases the line thickness, and forward/back increases/decreases the amount of lines. It's a bit of a cheat because, as I understand what's happening with the amount of lines, I'm simply pushing them off the visible window to get fewer of them, but it looks like it's doing what I was after so I'm happy :)

I'm now implementing live granular synthesis for the 4 performers, also to be controlled using my arduinome. So it's all coming along great!

Thanks again for all your help!
