I wanted to share this fantastic icon work that was created by an absolute master. It's only 4 colors, but the mind-bending dithering work creates an optical illusion of much more.
And, it's animated.
To illustrate the 4-color marvel at work here, I loaded up the icon file in IconMaster for a closer look.
This really just blows me away. I've like to improve my own skills after studying this technique further. The broken vertical lines really add a lot of detail and texture. Just fantastic.
