10 Adobe Photoshop 7.0+ Brushes to roughly create the BGs I create in my Grunge/Abstract wallpapers.
Hint: Create a new layer and apply these brushes heavily and quite randomly. Then press CTRL and click the brushed layer and add any gradients in OVERLAYED blending mode. Enjoy!
The brushes are huge because I make wallpapers... It's better downsized than blown up.
(Please give credit to me if used.. I'd also love to see what you do with it. ^^)
