In February 2022, Don Knuth found a cool graph which contains all 4-vertex graphs as subgraphs. Furthermore, they can be visited in revolving-door Gray code order.
He reported about it in exercise 291 in pre-fasicle 7a, and asked if someone could make an animated video of it. This is my attempt at it.
Any remarks or suggestions for improvement are welcome.
Thanks. The original idea by Knuth was to have each vertex have both a separate tune and a separate instrument/timbre, with each combination sounding not too bad.
I couldn't make this sound good with 8 separate instruments, so I went for the next best thing: a single instrument, with each vertex playing one note (0->B, 1->C,...7->a).
