I personally just posted my first set of actions. Only a few of them so far, but I'm planning on releasing updates to my first collection.
They're unique. They aren't aimed at immediate color and hue alterations to the image but rather supplying the artist with a set of none destructive tools. I would really appreciate it if you'd take a look over here [link]
They are actions. You preload them into photoshop, and click the play button, and it performs all of the actions. These are bugged so I don't know how well the work anymore, but check out some of the others on dA.
