The graphical style of this image is very valuable, and I think will help inspire a new wave of OS design in the future. Your other images like this will do the same, and I've seen similar graphics on various other accounts here at dA.
I collect vast amounts of flow charts, mind maps, and concept sketches of future operating systems. I help design Linux desktop interfaces, and I've been hoping to contribute to the Google supported gOS derivative of Ubuntu OS. All that I do, actually pales in comparison to this image.
This is really inspirational. Thank you for making this.
