Icons
I have designed thousands of icons and graphics over the course of the ten years or so that I have been at Xerox. Here are some examples.
16-color icons
Back in the day, windows apps safely supported only 16-colors. (Not 16-bit but 16 specific colors) When there were multiple versions of windows around, we had to design to the lowest common denominator (windows 3.1) and stick with the 16-colors so code did not need to be recompiled and re-tested.
