Here in the future, artists conspire underground:

“Stepping into the station was like stepping into a space outside of time. Utterly devoid of light, there was no way to mark the passage of time except for the occasional dull roar of a train in the distance. I had only a flashlight to light my way, yet it only barely cut into the inky blackness of the station. The air was cool and damp. My every step kicked up swirls of the rail dust that blanketed every surface. If it hadn’t been for the reassuring presence of familiar art adorning the walls, I might have quickly succumb[ed] to the illusion that I’d arrived amidst the remnants of a forgotten city.”

Is it, perhaps, a new downward trend?

Here’s some of the fine stuff, this by artist Jeff Soto. Photo by the above-linked blogger, who’s posted a large gallery of the works.
