Artists Tim Noble and Sue Webster find self-portraits in arrangements of domestic trash. Their Dirty White Trash (with Gulls) (1998, right) was contrived from the six months’ rubbish they produced while making it, a sculpture produced by the residue of its own composition.

More shadow art: Shigeo Fukuda, Larry Kagan, Richard Haas.

Somewhat related: Last year travelers from Washington state to Vancouver were surprised to discover this “negative space” billboard by the side of the road. It was created by Daniel Mihalyo and Annie Han of Seattle-based art collective Lead Pencil Studio. Most billboards draw the eye away from the environment; this draws the eye to it.

(Thanks, Alex and Bob.)

Willard Wigan makes tiny art. His sculptures are so small that they’re often presented literally in the eye of a needle; the painstaking work requires him to work late at night, when traffic vibrations are minimal, and to slow his own pulse so he can sculpt between hand tremors.

“It began when I was five years old,” he said. “I started making houses for ants because I thought they needed somewhere to live. Then I made them shoes and hats. It was a fantasy world I escaped to. That’s how my career as a micro-sculptor began.”

His tools include a paintbrush fashioned from a hair from the back of a dead fly. “I have to kill my body,” he told the BBC in 2009. “It’s almost like a dead man working. It takes so much out of you it almost sends you mad. I have passed out doing this work.”

This is startling — in 1500 artist Jacopo de Barbari produced an aerial view of Venice, assembled from six woodcuts on large sheets of paper. The full image fills nearly 4 square meters; it was probably assembled from sightings taken by surveyors in bell towers around the city.

The artist’s meticulous attention to detail is reflected in the flat roof on the bell tower in St. Mark’s Square, which was added after a fire in 1489. When the tower was restored in 1514, the woodblocks were updated to reflect the change.

When James Thurber tried to improve his drawings, E.B. White told him, “Don’t do that. If you ever got good you’d be mediocre.”

The German comedian known as Loriot (Vicco von Bülow) used to perform a narrative version of Camille Saint-Saëns’ The Carnival of the Animals with members of the Berlin Philharmonic Orchestra, using words to convey music. “His style enters the fairy-tale world the composer has portrayed musically,” writes Siglind Bruhn in Musical Ekphrasis (2000). “He sees and hears the orchestra’s depictions from the inside. Here, the verbal medium happily supplements the little details that might otherwise escape the music listener.” Here’s part of Bruhn’s translation:

A wood-ant, no longer in her prime, taps the giant ant-eater in front of her on the shoulder. ‘Excuse me, I cannot see anything if you keep your hat on,’ Grumpily the ant-eater takes off her headdress, an unwieldy contraption braided from wild asparagus and chicken feathers. ‘Thank you!’ says the ant. Then she lets her eyes wander across the jungle clearing. On the arena seats alone she counts 4791 strangely costumed animals, not to mention the innumerable monkeys and birds that are crowding the overburdened treetops.

Just now there is a stir of anticipation, for the moon is ascending from behind the branches of a mango tree to signal the beginning of the festivity. ‘I think I hear something,’ says a pigeon and she isn’t altogether wrong, for over there near the entrance, in the twigs of a bare oak, sixty-four horned owls take up their instruments. And now the marabou raises his baton, the two squirrels at the pianos lower their paws into the keyboards … and then he enters, with all the members of the royal family: His Majesty, the Lion.

Accompanied by moderate applause the lion has ambled twice around the arena, looking rather bored as he waved to the crowd. Together with his spouse, his three sons, one daughter, five cousins, and an imperfectly colored aunt, he has then taken the seats of honor and closed his eyes. …

Gustav Holst created a unique effect for the conclusion of his orchestral suite The Planets. He stipulated that the women’s chorus was “to be placed in an adjoining room, the door of which is to be left open until the last bar of the piece, when it is to be slowly and silently closed,” and that the final bar, performed by chorus alone, was “to be repeated until the sound is lost in the distance.”

Although familiar today, the effect thrilled audiences at the time. In her 1938 biography of her father, Imogen Holst recalls a 1918 performance by the London Symphony Orchestra: “But it was the end of Neptune that was unforgettable, with its hidden chorus of women’s voices growing fainter and fainter in the distance, until the imagination knew no difference between sound and silence.”

In 1961, Robert Rauschenberg was invited to participate in a Paris show in which artists were to exhibit a portrait of gallery owner Iris Clert. Rauschenberg sent a telegram:

THIS IS A PORTRAIT OF IRIS CLERT IF I SAY SO

Was he right? Perhaps so: Three years later, Parisian performance artist Ben Vautier sat down in a street in Nice holding a placard in his lap. The placard read:

Regardez moi cela suffit je suis art.

That means, “Look at me. That’s all it takes; I’m art.”

In 1975 Denys Parsons devised a surprisingly simple way for nonmusicians to record melodies — write an asterisk for the first note, then hum the tune and decide whether each subsequent note goes up (U), down (D), or repeats (R). The first two phrases of “Happy Birthday,” for instance, look like this:

*RUDUDDRUDUD

(“* repeat up down up down down repeat up down up down”)

This is surprisingly effective — Parsons, who spent five years indexing practically every well-known classical theme from the 16th century onward, wrote, “I continue to be astonished that such a simple test, taken to the sixteenth note (or less), should be adequate to distinguish more than 10,000 classical themes.” Can you identify the eight famous classical melodies below?

1. *RRDURRD
2. *RUURURDRDRUURURDR
3. *RUURDDDDRUURDRURUURDDDDRUUDDR
4. *DUDUDUUUDDUDUDDUD
5. *DUDDDDDUDDUDUDU
6. *UDUUDUDUUDUDUUDUDUU
7. *DUDUDUDURRRRRRRRDUDU
8. *RRRRRRRUUUDRRRRUURDDD
