Here's a question: what makes art... well, art?
There are probably an infinite number of answers to that question. Ever since 1917, when artist Marcel Duchamp signed a urinal, called it 'Fountain', and placed it in an exhibition, it seems like the definition has been wide open.
Abstraction, absurdist art, and performance art have all become part of the art world alongside representational painting.
But can anyone be an artist? Or for that matter, become a work of art?
That's the question YouTube users Doug and Mikael try to answer with this video. The duo invaded the Tate Modern and Saatchi galleries in London, England, armed with only a yellow ping pong ball each.
Once inside, each performer pops the ball in his mouth and positions himself somewhere in the gallery as if he's a piece of artwork.
And then the gallery-goers start flocking around, taking pictures and even posing for pics alongside Doug and Mikael.
Commenters on the video seem to be divided on what it means. ShotTower1 says "This! This right here is the problem! Critics love to think they are smarter than anyone else, so they look at a canvas with a red spot painted on it and read some deeper meaning which isn't there.
"Art should take talent, skill, practice," ShotTower1 continues. "If everyone can do it then it's not art."
But others see the video itself as a work of art: "Art is relative. Art makes a statement. Art invokes and evokes emotion. This is art. Nice work guys" says commenter tantoedge.
What do you think? Does this video make a statement about the critical establishment, or is it a work of art in its own right - or do you see it in another light?
If you're wondering how abstract art came to be in the first place, MOMA has released a cool interactive infographic tracing the connections between the many artists who helped pioneer the movement.
It's called "Inventing Abstraction 1910-1925", and it offers an in depth look at the many artists who explored abstract forms during the period, and their influence on one another.
The infographic is part of an exhibition of abstract works currently showing at the gallery.
