Ok, see this little, little squares? how can I make that? (icon by reibnitz )
Lately I've notice in a lot of icons this effect and I can't figure out, it is a pattern or a texture?
here are some more examples: (icons by darknumb )
I would really apreciate if someone can guide me to a tutorial or could explain how exactly can I get this effect :) (I'm using Photoshop CS 2). Thanks in advance! ;)
