Old memories:

Graphic workstations appeared during my student days. We were taught a method called SSA, Structured System Analysis, were "processes" (not in the software sense!) were drawn as boxes with round corners.

For his thesis work, one of my classmates implemented a tool for SSA development on the brand new PERQ workstations. You could control every single pixel on the screen! But that was all. Not even a library function for drawing a straight line; you had to program that yourself. But that is straightforward.

Then comes the round corners. In those days, the computer graphics course taught us how to map a function to pixels. So that is straightforward. Except that methods for drawing mathematical curves required trigonometric functions. PERQ provided nothing of that sort. We learned to do that in the Numerical Methods course. So that was straightforward. Except that those methods assumed floating point. PERQ had only integer arithmetic. So you had to design a software floating point format and implement the basic mathematical operations on it. Straightforward, right?

My classmate did implement a floating point package. Then a trigonometric library. Then a graphical library for drawing curves defined by trig functions. On top of that, a tool for designing SSA diagrams, with animation of document flow through the model.

I think that classifies as a "spectacular achievement" for a Master thesis. It may come as no surprise that he is now a highly respected professor in the Computer Science department of the Technical University.
