The DecoBrush is a very flexible 2dTool that can be customized many different ways. Experiment with the DecoBrush-Modifier's sliders and the Tile Texture button.
Also, try combinations of the material, RGB and Zadd Transform buttons. Of course the DecoBrush strokes can be changed dramatically by just changing the assigned materials and lighting.
I've started using the DecoBrush with Alphas, particularly from the wonderful collections posted by Polaris30 a while back. He put up some great tilable alphas that are perfect for the DecoBrush.
Watch out though, DecoBrush experiments can be a big time-sink
