So this solution is until (if ever) someone creates an actual fully functional app as I described in my recent journal.
Me and Xyrfo decided to recreate this for rainmeter. What started out as just a bunch of icons is now a highly customizable and functional icon suite. Complete with automatic resolution-aware icon rearranging (xyrfo pushing rainmeter to it's edge again).
Must say, this turned out better than expected, and I think a lot of you will like its functionality as well as its looks.
The only thing we can't be sure about is folders.
Comments and suggestions are welcome!
P.S> That's actual aero blur behind the icons
Also I included some of the graphics, in case anyone who's interested in making the real thing wants them.
