This brush changes its angle according to how you are brushing. I used information gleaned from
this thread by Punkie to make it, although I used GAP. It has 100 layers and rotates the brush by 3.6 degreees each layer so it can pretty closely follow the angle of your brushing. Each of the three "strokes" in the example below was done with a single stroke of the mouse.
Here is the link to the brush file.
