A set of Photoshop brushes made up of a bunch of different "micro patterns" - pixelated patterns that would work well for any number of purposes. You could use the different "dots" brushes to add to an image and make it look like newspaper print, for example. If you're looking for something seamless, check out these same micro patterns as a PS pattern set!

Includes: circles, dots, dashes, grids, squares, scales, twirls, waves, zigzags, and lots of lines!
