People have been de-robing and getting themselves immortalised in their birthday suits - all in the name of art, of course - for thousands of years.
It's not a new trend, though commissioning an oil painting / marble statue of yourself in the buff is, these days, probably quite pricey.
So perhaps it's no surprise the 'one finger selfie challenge' is now a capturing the public's imagination.
Cheaper and less time-consuming than sitting for an artist, it's the sort of trend the internet loves: Slightly mad and with plenty of scope of error.
But what does it entail? Is it easy to master and, above all, why?
Firstly, here is what it looks like
It initially took us a while to get our heads around it, but one participant got a solid 18 likes on Instagram for this, and we now think we understand.
Using solely their index finger, females only (by the look of it) stand in front of a mirror naked and take a photo with that finger very strategically placed to protect their modesty.
One millimetre out and it's game over.
Cementing the fact this is now a trend is YouTuber Aimee Davidson who has kindly made a video showing us all how to do the challenge.
The concept, news.au reports, "originated with an illustration by Japanese anime artist Sky-FreeDom, which shows a naked girl using one finger reflected in a mirror to cover both her breasts and private parts."
As with every trend , however, there are of course questions raised - and a backlash.
Weighing in on the craze was Teen Vogue , who warned that while being body confident enough to take is part is no bad thing, it does open the door to feeling body shamed.
Much like mermaid thighs, thigh gaps and Kylie Jenner lips, the whole premise relies on your body being a certain type, which not everyone will have.
Which is, of course, absolutely fine and normal.
