Hmpf. It’s now January and I’m still doing Advent. Still, I was determine to push ahead. Then I got stuck good and proper on Day 19 - though to be fair the whole Log4shell dumpster fire was taking up a lot of time, so I decided to skip it for now. Day 20 of Advent of Code 2021 was all about transforming images. What made it slightly more complicated was the fact that the images were nominally of infinite size.
