If you want to see some crazy math stuff, look into axiom[0]. It's an open source computer algebra system programmed in Common Lisp. The manuals for the project add up to be ~10,000 pages[1]. It's all done in the literate programming style and it's being actively developed. I am probably going to write an idea up in a month or so, but if a computer programmer wants to learn some advanced Math beyond first year calculus quickly, downloading axiom and working through the first tutorial is the way to go.
