Stencil shader

I think this one looks quite good, it looks like a stencil to me. It could probably do with a bit harder colouring, and the lines ideally need to be more pointy, but other than that, it works. What I would really like to do is add some randomness into the equation, like moving the stencil image a little in random directions, and comp in paint underneath, so it looks like it being sprayed onto the wall, and then painted over, then the next frame sprayed on top of that.....
