Most mind-blowing program for your favorite calculator

Hello!

I still have four cards for my Ti59 that were required to numerically solve a system of differential equations. This must have been around the same year, 1982 or 83, part of an excercise for a university course "numerical methods for solving differential equations in engineering" (or similar).
The alternative to swapping cards on my Ti59 at home would have been to queue in front of a keypunch at the university computer center.

That was probably the most intense thing I ever did with a programmable calculator, although I would not call it "mind blowing" as in the thread title. Rather brute force or "not using the right tool for the job".
