When you look at Rayo Casablanca’s asshole, your first thought may be that it resembles a very complicated math problem. It isn’t exactly what you’d expect from an author whose debut novel is called 6 Sick Hipsters. But then again, he also contributes to magazines like Geek Monthly, so I suppose it’s not entirely out of character. It’s possible that his anus just represents one side of his personality; the “math nerd” Yin to his “sick hipster” Yang.

“The first draft was something best described as dirty geometry,” Rayo told me. “It didn’t really work – too literal. I wanted to go with something that captured the spellbinding inscrutability of my arsehole. And frankly, there’s nothing more irritating and fascinating in that vague sort of way than connect-the-dots.”
