It’s a classic of low literature:
There was a young man of Devizes
Whose balls were of different sizes:
The one was so small
’Twas no use at all;
But t’other won several prizes.
But what if he had been a young man with balls of different colours? This is a core question I want to interrogate issues around in terms of the narrative trajectory of this blog-post. Siriusly. But it’s not the keyliest core question. More corely keyly still, I want to ask what a fractal phallus might look like. Or a phrallus, for short. The narrative trajectory initializes with this fractal, which is known as a pentaflake (so-named from its resemblance to a snowflake):

Pentaflake — a pentagon-based fractal
It’s created by repeatedly replacing pentagons with six smaller pentagons, like this:

Pentaflake stage 0

Pentaflake stage 1

Pentaflake stage 2

Pentaflake stage 3

Pentaflake stage 3

Pentaflake stage 4

Pentaflake (static)
This is another version of the pentaflake, missing the central pentagon of the six used in the standard pentaflake:

No-Center Pentaflake stage 0

No-Center Pentaflake stage 1

Stage 2

Stage 3

Stage 4

No-Center Pentaflake (static #1)

No-Center Pentaflake (static #2)
The phrallus, or fractal phallus, begins with an incomplete version of the first stage of the pentaflake (note balls of different colours):

Phrallus stage 1

Phrallus stage 1 (monochrome)

Phrallus stage 2

Phrallus stage 3

Stage 4

Stage 5

Stage 6

Stage 7

Stage 8
And there you have it: a fractal phallus, or phrallus. Here is an animated version:

Phrallus (static)
But the narrative trajectory is not over. The center of the phrallus can be rotated to yield mutant phralloi. Stage #1 of the mutants looks like this:

Phrallus (mutation #1)

Phrallus (mutation #2)

Phrallus (mutation #3)

Phrallus (mutation #4)

Phrallus (mutation #5)

Mutant phralloi (rotating)
Here are some animations of the mutant phralloi:

Phrallus (mutation #3) (animated)

Phrallus (mutation #5) (animated)
This mutation doesn’t position the pentagons in the usual way:

Phrallus (another upright version) (animated)
The static mutant phralloi look like this:

Phrallus (mutation #2)

Phrallus (mutation #3)

Phrallus (upright #2)
And if the mutant phralloi are combined in a single image, they rotate like this:
