UPDATE: 5.22.13 Made some significant changes to the original set, which I realized was a bit "overwrought"...I had complicated the representations. So Went through and simplified. Hope you approve.
A personal take on the Metro look for the Adobe Creative Suite: Starting with the Office 2013 form but using rounded corners and soft shapes rather than the squared, sharp corners.
In three different coloring styles: Solid backgrounds, Outlined backgrounds, and Freeform
PNGs are in both 512 sq pixels and 128 sq pixels.
