5 Constants: P i = bass; e = piano; i, for "practical"
reasons the square root of 2 for this sonification, = trumpet
and sax; 1 & 0 = metal mallets; 1 = whistle and, of course,
0 = the cuica.
part of me that says this video is too full of gratuitous graphics
and it tips the sound/visual balance too much to the visual. I
mean, dancing fonts? On the other hand, Euler wrote over 500 books
in his lifetime (yes, 500!) and his work touches on nearly everything
modern, e.g., electronics, hydrodynamics, elasticity, radio transmission,
networks, etc. So, I picked the fonts and their movement with
that happy thought in mind.
