This Is Clever (8 Photos)

The street is part of the design.

A wave-break block becomes a Rubik’s Cube. A bollard turns into an octopus, and a crack in a Sydney wall opens into a tiny nightclub. Elsewhere, a transformer house becomes a birdhouse.

🧩 Eroded Rubik’s Cube — By an Unknown Artist at Scheveningen Harbour, Netherlands 🇳🇱

Painted squares turn one of the harbour’s concrete wave-break blocks into a weathered Rubik’s Cube. Roel Wijnants photographed the intervention in Scheveningen on August 26, 2013, but the artist remains unconfirmed.

💡 Puzzle Fact: The standard 3×3 Rubik’s Cube has 43,252,003,274,489,856,000 reachable positions, yet every one can be solved in 20 moves or fewer when any turn of a face counts as one move. The 2010 proof used about 35 CPU years of computing time.

🐙 Painted Octopus — By Martin Shannon and Lumen Street Theatre in Limerick, Ireland 🇮🇪

The blue bollard becomes the octopus’s head while eight painted arms spread across the pavement. Martin Shannon and Lumen Street Theatre created it for a Riverfest 2022 scavenger hunt commissioned by Limerick City and County Council along the Three Bridges Walk. Shannon said the octopus was an inside joke among people who swim in the River Shannon. Photo by James Gammell.

💡 Cephalopod Fact: About two-thirds of an octopus’s neurons are located in its arms rather than its head. Its nervous system is distributed through the limbs instead of being concentrated entirely in the central brain.

☕ “biberstumpf kaffeeklatsch” — By David Zinn in Michigan, USA 🇺🇸

A chalk beaver appears to sit inside a hollow tree stump, holding a mug of coffee. Zinn titled the 2020 work “biberstumpf kaffeeklatsch”, letting the cut wood provide both the room and the frame.

💡 Language Fact: Kaffeeklatsch is a German compound of Kaffee (“coffee”) and Klatsch (“gossip”), meaning a social gathering over coffee. The second half of Zinn’s title therefore implies conversation as well as coffee.

🕊️ “Sembrando Paz” — By Adry del Rocío and Carlos Alberto GH in Culiacán, Mexico 🇲🇽

A mother and two children, white doves and flowers wrap around the apartment building’s windows and air-conditioning units. SUMA explains that the artists used anamorphosis, so the composition resolves from a specific viewing point, and that the family scene reflects the idea that peace begins in homes and childhood. Created with Vamos Pintando, the mural stands on Avenida Álvaro Obregón in Colonia Gabriel Leyva, beside Hospital Civil de Culiacán.

💡 Award Fact: Adry del Rocío and Carlos Alberto García Hernández are siblings, and Street Art Cities users voted “Sembrando Paz” the best mural of December 2025. The public vote also included works from Colombia, the United States, Australia, France and Spain.

🍂 “In Which Nadine Amuses a Dragon and Makes Autumn Happen” — By David Zinn in Ann Arbor, Michigan, USA 🇺🇸

Nadine stands beside a green chalk dragon laughing on its back. David Zinn called the scene “In Which Nadine Amuses a Dragon and Makes Autumn Happen”; the bank of real leaves beside the dragon completes the scene.

💡 Character Fact: Nadine is a recurring figure rather than a character created for this scene. Zinn describes her as “a mouse of adventure” and lists her with Sluggo and Philomena among his most enduring characters.

🐦 Eurasian Blue Tit — By JanIsDeMan in Dinteloord, North Brabant, Netherlands 🇳🇱

The brick transformer house becomes a birdhouse: an adult blue tit carries flowers to chicks peering from the round opening. JanIsDeMan’s own post places the mural in Dinteloord in 2021, while local reporting says it was conceived as an ode to the Bloemendijk and its biodiversity. The work stands at the beginning of the Bloemendijk.

💡 Bird Fact: The crown’s blue coloration includes an ultraviolet component invisible to humans. Both male and female blue tits have ultraviolet-reflecting crown feathers, and studies link this UV signal to mate choice.
