The mathematics of album cover art.
That's "the mathematics of album cover art."
Here's an article by David "Zyzzyx" Steinberg regarding the cover art he provided for Trey Anastasio's bonus EP, 18 Steps. 18 Steps comes bundled with pre-orders of the full-length album Bar 17. Got that?
The EP isn't out yet and the final cover art--so far as I know--hasn't been leaked. So what's so special about this? Why a full article?
He was looking for something mathematical that would tie the two albums together; it should be confusing but yet actually mean something. [...] After an initial attempt at finding some fun facts about 17 and 18 - did you know that 17 is an unlucky number in Italy because XVII can be rearranged as VIXI which means, "I lived?" - the obvious approach came to mind. Let's try to take 18 steps to move from 17 to 18 using as much math as possible.
In this article, he describes the exact mathematical process he used to do this, which, as a byproduct, gave 18 Steps its cover art.
Almost makes me wish I could do math.
