I remember I was on a very big complicated project doing some groundbreaking stuff on single sourcing multiple meda a decade ago and a couple years ago I asked someone else on the same project what was the best part about it for them and it was when they had made some svg conversion algorithm for generating all the various colored backgrounds and icons that any dynamically generated website needed when a customer decided they wanted to generate a website for their data.

It was a ridiculously trivial part of the whole, but that was what had really made him happy.
