No ordinary objects Abandoned by the world, no longer of use, but still carefully repaired and preserved, these were no ordinary objects. The reasons for their maintenance remain a mystery. At this point, they could only be described as "art". No—not so much "art" as something that exceeds art... Hyperart. Genpei Akasegawa & Matt Fargo, Hyperart: Thomasson artrepairthomassonsobjects
Hyperart: U.S. Rail The steepest grade on U.S. main-line track is at the small town of Saluda, on a Norfolk Southern route between Spartanburg, South Carolina, and Asheville, North Carolina. The grade goes on for three miles at a slope of 4 or 5 percent. Trains have not been running on the line since 2001, but the tracks are still maintained.

Thomassons This was 1982, the year that Gary Thomasson was batting cleanup for the Yomiuri Giants. Thomasson had the unfortunate nickname of "The Electric Fan", which, if you think about it, was exactly what he was. Night after night, he stood in the batter's box, whiffing mightily at the ball, down on three strikes every time. He had a fully-formed body and yet served no purpose to the world. And the Giants were still paying a mint to keep him there. It was a beautiful thing. I'm not being ironic here either. Seriously, I can't think of any way to describe Gary Thomasson but as "living hyperart". Genpei Akasegawa & Matt Fargo, Hyperart: Thomasson sportsthomassons
Wang tiles Wang tiles (Hao Wang, 1961) are a class of formal systems. They are modelled visually by square tiles with a color on each side. A set of such tiles is selected, and copies of the tiles are arranged side by side with matching colors, without rotating or reflecting them. The basic question about a set of Wang tiles is whether it can tile the plane or not, i.e., whether an entire infinite plane can be filled this way. The next question is whether this can be done in a periodic pattern. In 1966, Wang's student Robert Berger solved the problem in the negative. He proved that no algorithm for the problem can exist, by showing how to translate any Turing machine into a set of Wang tiles that tiles the plane if and only if the Turing machine does not halt. The undecidability of the halting problem then implies the undecidability of Wang's tiling problem.
