help with this effect

http://img227.imageshack.us/img227/8412/effect1na.jpg

i came across this website by accident and i loved the effect at once, i have seen this style alot before and it looks to me like a painting with a half dried brush, which i think it looks really cool

so could anyone teach me how to do this kind of effects on buttons and texts? i would like to adapt it on my website, or a tutorial would be even better :)

thanks alot

Its just grunge brushes on the eraser tool i think

pretty much

thanks for your replies, i've tried a few grunge brushes from deviantart.com and used with the eraser tool, after playing around for a while i still cant get anywhere close to that look :( it would be lovely if you guys could suggest a few specific grunge brush for this effect :) or even better, point me to the direction of how to make them myself :)

thanks in advance

Goto http://metal-cx.deviantart.com

Then goto "Scraps"

Look for his "Grunge and Shit" brushes. They are really good for this.

i'll try them out now, thanks
