The inspiration for the icon part was a stylized robotic hand. I wanted to give it a sense of motion and mobility, almost like a computer controlled robotic arm. I've seen robotic welders in the automotive industry that operated similar to this fashion.
I had initially put it on a 45 degree angle in order to simulate a high level multi-axes type of cnc application. I thought it looked kind of cool so I submitted it to you.
I can easily do the solid colors like you requested, and of course you could also have it the way it is now for web and online uses.
Let me know if there's anything I can do.
