This is really, really amazing. Great work. I wish there was a way to donate.
The only thing that would make it better is if you could get the background blur effect like on the default side dock. It's a subtle but important difference, imo. Especially for those of us going for the iOS7 look.
Yeah after looking at it I think my 10.9 style dock is pretty inaccurate. I seriously doubt I'd be able to figure out how to add transparency but I think I'll adjust the alpha and add shadow to some of the dock versions to make it feel a bit more like the normal dock.
