I've seen a couple of very nice examples of artists making great images with processing. It made me wonder how the image was made. Particularly i would very much like to know more about the process behind making images where the pixels are sort of smeared out over the canvas.
These fantastic artworks explain it much better than I do with words: http://adamferriss.tumblr.com/tagged/processing

Would be great If anybody could point me in the right direction!
