In 2005 the Austrian art group Gelitin offered the “Tantamounter,” a sealed wooden box the size of a small house. Visitors could place any object into a hatch, and within an hour a handmade “duplicate” would join it. More examples.
In 2004 they built a roller coaster inside a Milan gallery (below).
Alexandra Kehayoglou makes carpets that evoke the topography of her native Argentina: grasslands, waterways, and glaciers. Her family opened a conventional carpet company there in 1956, and she discovered she could use scraps from their work to create “tactile canvases.” Each piece is composed by hand from discarded or surplus wool on a vertical frame, using a tufting gun and carpet scissors.
Her work often draws attention to natural areas altered by human activity in Argentina, such as the Raggio Creek north of Buenos Aires, destroyed for a shopping mall, or the Santa Cruz River, the last free-flowing wild river in the country, proposed site of two major hydroelectricity dams.
“It’s hard for people to understand that a rug can be art,” she told the New York Times. “But maybe that’s changing.”
Because he wrote for player pianos, Conlon Nancarrow could demand more exacting performances than other composers. His Study No. 41 is in three parts for two pianos. The first canon has a time signature of

French street artist JR has twice transformed I.M. Pei’s iconic pyramid at the Musée du Louvre in Paris.
In 2016 he made it disappear by overlaying one face with an image of the background facade.
And just this month (below) he applied 2,000 stickers to the surrounding pavement to create an anamorphic illusion in which the pyramid seems to rise from a crater.
The paper stickers were quickly destroyed by wandering tourists, but that was expected, he said. “The images, like life, are ephemeral. Once pasted, the art piece lives on its own. The sun dries the light glue and with every step, people tear pieces of the fragile paper. The process is all about participation of volunteers, visitors, and souvenir catchers.”
Anthony Howe creates wind-driven sculptures that somehow evoke both marine biology and alien machines.
“I attempt, with an economy of means, to construct objects whose visual references range from lo-tech sci-fi paraphernalia to microbiological or astronomical models,” he says. “Utilizing primarily stainless steel armatures that are driven either by hammered curvilinear shapes or flat fiberglass covered discs, I hope the pieces assume a spare, linear elegance when conditions are still, mutating to raucous animation when the wind picks up.”
In a 2009 study of responses to music, neuroscientist Valorie Salimpoor and her colleagues asked participants to bring in 3 to 5 pieces of “intensely pleasurable instrumental music to which they experience chills.” Then they measured their physiological response as they listened. They found that the “chills” effect is real — when the subjects reported that their pleasure at the music was highest, so was their sympathetic nervous system activity, a measure of emotional arousal.
One byproduct of the study is a list of more than 200 chills-inducing moments in music of various genres, with precise timestamps of the crucial points:
| Composer/Artist | Title | Chills |
| Beethoven | Piano Sonata No. 17 in D Minor (“The Tempest”) | 5:33 |
| Mahler | Symphony No. 1 – Movement 4 | 5:42, 9:57, 15:15 |
| Charles Mingus | Fables of Faubus | 0:20, 7:10 |
| Stan Getz | Round Midnight | 1:26 |
| Pink Floyd | Shine on You Crazy Diamond | 5:00 |
| Phish | You Enjoy Myself | 10:50 |
| Cannonball Adderley | One for Daddy-O | 0:40 |
| Los Angeles Guitar Quartet | Congan | 2:09 |
| Crowfoot | Larks in May | 0:10, 2:00 |
| Howard Shore | The Breaking of the Fellowship (film score) | 0:10, 0:55 |
| Dave Matthews Band | #34 | 1:40 |
| The Dissociatives | Paris Circa 2007 Slash 08 | 1:30 |
| Brad Mehldau | Knives Out | 4:45, 7:25 |
| Explosions in the Sky | First Breath After Coma | 2:25, 3:30, 8:10 |
These won’t work for everyone — music tastes are notoriously idiosyncratic — but it’s interesting to see what people find moving. The full list is here (Table_S1). (Note too that the timestamps relate to a particular recording, so consider them approximate in e.g. classical music.)

Manfred Laber’s public art piece in Wemding, Germany, doesn’t look much like a pyramid yet. That’s because a new concrete block is laid only every 10 years; the structure was begun in 1993 and will be completed in the year 3183, when the 120th block is placed at the top.
Altogether that’s 1,200 years, the town’s age when Laber conceived the project and laid its foundation.
Brad Spencer’s sculptures are both familiar and foreign — they’re fashioned from one of the most common building materials, but they leave viewers wondering how this was accomplished:

To pass the time while waiting in the trenches of the Argonne, French infantryman Hippolyte Hodeau engraved the names of his daughters in chestnut leaves.

Austrian artist Peter Kogler uses twisting lines and geometric shapes to generate dramatic illusions in ordinary spaces.
“The black-and-white grid provides a maximum contrast which has a very strong visual presence,” he says. “The structure of the image is comprehensive and completely surrounds the beholder. In a sense, you are standing in the picture, and the work can be experienced physically.”
