Its like dancing, the more effortless it looks, the harder it is to do. Sometimes takes a lot of math to design the ideal simplest possible part rather than just hacking some kind of brute force beast together.

"Simplicate and add lightness" is a cool aerospace engineering slogan that's been attributed to almost everyone in the biz who is cool, although it actually comes from a Ford engineer named Stout (like the beer), at least as I recall it. I like this slogan, and its the same general topic we're discussing, but I think the joke is more effective because its funny.
