Grimes has explained the design process behind her "beautiful alien scars" tattoo on Instagram.
Elon Musk's girlfriend, 33, revealed her tattoo on the social media website on Sunday, prompting a mixed response from her fans, with some describing it as "beautiful" and others comparing it to spaghetti.
The unusual tattoo is made of white ink, and Grimes shared a breakdown of artist Nusi Quero's design process - a process she was clearly pleased with, having dubbed him "an alien brain."
Check out Grimes' new video on her tattoo below:Nusi explained that he and Tweak T co-designed the tattoo, and this took place after he was sent "base shapes" on an iPad by Tweak T, which he went on to embellish via a mathematical process.
He wrote: "Drew the base shapes on an iPad and then emailed me the image file. I turned it into 3D geomotery, selected vertices on the shape and guided and drew the embellishments along and around the shapes that he laid down first...
"[He did these] with a series of procedural operators (math rules) in a way that I felt spoke to his shapes and Grimes. I then sent it back to him as a png overlay and etc etc and they went in on it immediately full on 1 take 1 session. Ahh. [sic]"
Pocedural operators are "a general imperative programming device."
"A procedural operator is analogous to the mathematical notion of a 'functional operator', and can be described in terms of a computational process which can be initiated, suspended, resumed, and terminated," Science Direct reports.
Alongside Nusi's post, Grimes shared another photo of her new tattoo in all its glory.
The singer, who welcomed her first child with Musk last year, captioned the first shared snap of her new tattoo: "Full back in white ink by @tweakt w sum help from the alien computer brain of @nusi_quero
"Don't have a good pic cuz it hurts too much and I need to sleep haha, and it’'l be red for a few wks , but gna be beautiful alien scars [sic]
"Hope everyone's having a good day."
While alien scars might not be to everyone's taste, this tattoo comes after Grimes revealed that she plans to relocate to Mars to help colonize the red planet after she turns 50.
