I wanted to thank you so much for posting this that I actually joined the site to do so. I saw this image as a screen shot from someone's Android on another user forum and inquired as to who the artist was and where could I find the image for myself.
It turns out that the one who posted it wasn't showing his phone background, but the background from the phone of the developer of the app Beautiful Widgets so the poster didn't know its origins.
So thank you, again. I now have it for my own, but I'd still love to know the artist's name or where it came from.
