My jaw dropped wide open at first :) I thought someone joked with you and published it on your behalf :)
but laughs aside - this artis is brilliant, not only did the artist make an ordinary toilet booth a "gallery" of art, In a way that makes you shocked, then amused, then interested - he also intends, in my opinion, to deliver a very clear message - once you think about that it might seem obvious :)
My thoughts are based on the book (don't be shocked please -that book really exists, it's philosophy, and it was translated to many languages) "History of Shit" by the French psychoanalyst Dominique Laporte (https://en.wikipedia.org/wiki/History_of_Shit):
Laporte claims that the important message isn't about the excrements themselves, it's about our attitude toward it - the shit has transformed from being a stinky, unwanted thing that causes disease and stench and that the society try to hide to something that in modern ages the man has taken the courage to face and conquer the aversion he feels toward it and turn it to his own use - he recycles it and uses it to fertilize his lands, he uses the excretions to produce fuel (google it :) - for him, shit has no smell, it is a tool to make money, and money has no smell.
this art is a metaphor for modern times, an evolvement of the idea we mentioned - it's the embodiment of capitalism - when people have no borders in their way to acquire money and assets and they will do anything for it,things that compare to them excretion recycling might look like nothing, and it became casual - just like the artist chose to put his golden work in an ordinary publish toilet.
This is actually a brilliant work and a gifted artist who wanted to deliver a clear message, that's how I see it :)
thanks velimir - that was extraordinary!
