IIRC there is prior art in this direction - I saw a machine in the
London Science Museum that does this. Victorian, I think. I forget
exactly how it works; suffice it to say it seems "obvious" after you've
been told. ;-)

You mean Charles Babagge's Analytical Machine?

I'm sure you know the importance of Babagge's work that led to today's
computers. And Ada Lovelace...

Actually no - this device was hard-wired for the Fourier transform.

Well, yeah, even a moron like me knows of Babagge's work...
The computer, more than any other invention in history, appears to be a
device that no single person can really be said to have "invented". It
really was the result of many, many great minds.

You're not a moron, just hopelessly misinformed. ;)
