Math is fun. Math mechanics are yukky. It’s the paradox of my brain that while the concepts and patterns of math rule much of my creative thinking, I seriously can’t add or multiply to save my life. Just never, never ask me to recite the multiplication tables for 6 or 8. It’s just not gonna happen.
 But patterns are fun, and they make math fun. A few years ago I worked on a very mathy project using phrases and javascript rollovers to create a set of combinatorial statements. It’s still fun to play with.
