Moscow programmer Ani Abakumova makes portraits by spanning circular hoops with lengths of colored thread.

A computer dictates the placement of the threads, but she produces each portrait by hand.

Daniel Rozin makes interactive digital artworks that respond to the presence of the viewer, in many cases serving as mechanical or digital mirrors.

“In an interactive piece such as my Mirrors or Easel, the piece has no content without the viewer and the piece celebrates the likeness of the viewer,” he says. “This suggests that the important part of this equation is the person, not the artifact.”

Hawaiian artist Sean Yoro paints murals positioned near or in large bodies of water. He paints on the sides of shipwrecks, abandoned docks, and submerged walls, often on themes of climate change and rising sea levels, balancing on a paddleboard and using environmentally friendly materials.

“Combining both my art and environmental passions happened almost by accident at first, when I started creating murals along ocean walls,” he told the Met. “I always had underlying messages of sustainability and awareness, but this was the first concept I could literally combine these two aspects of my life influences into one. Every project since then has seamlessly integrated both values into their own unique stories naturally.”

One day his inventive eye fell on an old bicycle saddle and handlebars. Placing the handlebars at the back of the saddle in an upright position he created a bull’s head with horns. The illusion was striking and the virtuosity of the transformation conferred a kind of noisy notoriety on this Tête de taureau. When it was exhibited after the Liberation Picasso looked at it with an amused air. ‘A metamorphosis has taken place,’ he said to André Warnod, ‘but now I would like another metamorphosis to occur in the opposite direction. Suppose my bull’s head was thrown on the rubbish heap and one day a man came along and said to himself: “There’s something I could use as handlebars for my bicycle.” Then a double metamorphosis would have been achieved.’

Swedish graffiti artist Daniel Fahlström makes trompe l’oeil murals of mylar balloon letters — there are no balloons, just the two-dimensional painted surface, but the effect is stunningly deceiving.

“I’ve seen a lot of reactions from people, and the funniest one was when this old lady that wasn’t wearing her glasses, she was trying to go up and touch the balloons,” he told Business Insider. “That’s good if they think that’s real balloons. That’s my mission, to make them believe that.”

Building Blocks, by Kumi Yamashita. “I sculpt using both light and shadow. I construct single or multiple objects and place them in relation to a single light source. The complete artwork is therefore comprised of both the material (the solid objects) and the immaterial (the light or shadow).”

Margaret Isabel Dicksee’s 1893 painting The Child Handel is based on a story about the composer’s childhood:

Handel’s father strongly opposed the child’s passionate love for music, and the more his great gifts developed the more severely was he forbidden to occupy himself with music. The little boy was obliged to have recourse to subterfuge, and when his elders believed him snug in bed he used to steal on tip-toe to the lumber-room, where he had discovered an old spinet, on which he played softly to his heart’s content, alone and fancy-free. In one of these moments of enjoyment, when the divine genius spoke to the child, he forgot himself and played louder and louder — all the sound of the old spinet streamed through the silent night, waking the sleepers in the house, who believed that the angels were keeping vigil over the old town of Halle. But little George’s father bethought himself of the musical propensities of the boy, and, as the latter was not to be found in his bed, the lantern was lit and a search-party followed where the music led them. Alas! Poor George was found, severely reprimanded, and dismissed to bed.

This telling is from the Strand, April 1904. The story is disputed, but Handel did display enough skill as a child to induce Duke Johann Adolf I to recommend him for musical instruction.
