This is a set I've been working on in my spare time for quite a while now. I've been using them as my Dock-set as-long. The "rule" is that the shape needs to wrap around a core, and visibly fold behind it in some places. And be colourful. And big.
The full set is up at www.nimbling.com - I'm happy to update it if anyone is interested.
*PS* I'll make a custom icon in this style for the first one guessing all the software depicted ;)
*PS2* If anyone discovers a way to customize the Dock & Trashcan again, however difficult, I'm super interested.
