Thanks to mister John D. Cook, and its blog “The Endeavour“, I was able to sense what other people think about using computers to sketch earliest math ideas. I found reader comments especially useful as they revealed that there really are people who would use computer instead of a pencil in this early ‘mind-mapping’ stage. And the Math-o-mir is all about replacing your pencil.

By the way, I spend several more days optimizing the code (learned some tricks about overloading the new operator in C++).  No much gain, of course… If you write software to earn money, never optimize! You will spend a lot of time for minimal effect. Only make optimizations if you are proud of what you are doing.
