I've found it extremely interesting that some people have visual minds, and some people have visual minds. By this I refer to certain peoples' ability to see how a product will evolve over time, and how some people prefer to view that interaction visually, rather than through description.
The extent to which this is true is a fairly recent realization for me, and just serves to further prove the need for decent mockups and workable design as a prerequisite to architecture.
In my experience, developers seem to have an easier time than most in transferring the code-in-mind, or -on-screen, to the end product. That being said, true mathematicians seem to have an even easier time simplifying the complex. They can take concepts that are extremely foreign or amazingly complex, and make it possible for even small children to understand. The true teachers have a gift for simplicity.
Take Kalid Azad, whose site BetterExplained.com offers some great simplistic insights to deep mathematical concepts. I came across his guide to imaginary numbers as a 90 degree rotated dimension from the standard number line, and was amazed how simple it was to understand. The interesting thing is how he presents it as a parallel concept from negative numbers, and fits it instantaneously to parallel logic.
