sorry, totally forgot to give a proper intro.
As there is no actual paint transfer done its not going to be immediately 
obvious whats what.

 The point of the V is the point where the stem (and your tablet point) 
touches the medium. But like in real brushes the hairs are trailing it 
and doing the actual paint transfer.  That process is shown with 
the 'beak' of the V shape.

Note
a) pressing harder widens the beak of the V.
b) moving from left to right will make the brush hairs trail the stem, 
just like real brush hairs do.
c) when you move opposite the direction of the current hairs, for example 
after moving from left to right and then suddenly moving from right to 
left. Then the natural manner of working is that the hairs don't rotate 
around, they 'flip' underneath.  I tried to emulate that as well.

Last note; this is certainly not meant to be a perfect brush emulation. It 
took me one morning to whip this up, don't expect perfection ;)
