Suspiciously easy. I even included a free animation generator for your entertainment.
Love a good visualisation <3
I was gonna do the same later when some free time, was wondering if it generated some kind of image.
If you click the link on that post, you'll see that the test data does resolve to a (very low res) elf!
Now you're just showing off!
Edit: ooh, this makes it obvious that my puzzle input takes more cycles to reach the done state.
That's a great addition :D
Running my own input I also noticed that your solution is a lot faster than mine (processing each roll individually). I'll keep that 2D-rotation in mind for the future.
Yeah, that's one thing the gurus keep hammering home: anything you can move out of loop constructs (inc rows, partition, etc as well as the obvious do, repeat) and handle pervasively is a big win.
