Beautiful and disgusting at the same time.
It’s vandalizing public property in the same way that human shit vandalizes a lot of public property in SF. I don’t know which one is worse. One can be beautiful, the other is done because he has no choice.
For graffiti I’m in support of lashing or whipping the people that do this. It’s effective in Singapore. But then we lose all this great public art.
If they're not covering windows, signs or art, what is being vandalized? A blank slab of concrete performs its function equally well no matter the color.
