Recursion also helps in making a quick function to calculate factorials (which I used a lot in my Combinatorics class a loooong time ago). Congrats on the patent. For me I started with FORTRAN IV (66) on a Cyber, did FORTRAN 77/Ada/C/C++ on various flight sims, and now do C/C++/Python on various platforms. Fun stuff!
