Integrating the shadows cast by everything from stop signs to public benches into street art often requires the luck of seeing the piece in action at just the right time of day, when the shadow is in just the right spot for everything to line up as intended. Catching it in action feels like serendipity and adds a little bit of magic to ordinary urban settings. But in the case of this particular work of shadow art, you could literally stand in front of it all day and just watch it transform before your eyes. The lettering attached to the facade of a building in India’s Lodhi District changes its angle as the sun moves across the sky, acting like a sundial.

‘Time Changes Everything’ by Indian street artist Daku requires the sun’s harsh light in this location and the stark white facade of the building to even be visible to passersby, virtually disappearing on a cloudy day or at night. Get close to the wall and look up, however, and you’ll get a new perspective on the piece, viewing the words upside-down. The theme relates to the passage of time, with words including ‘age,’ ‘illusion,’ ‘season,’ aim’ and ‘memory.’ They start out in italics and then shift into prime legibility at noon before leaning in the other direction.

The installation is part of the first dedicated public art district in India, turning the neighborhood into a gallery that’s available to everyone. ST+ART India invited 25 local and international street artists to contribute to the project, which aims to make art accessible for wider audiences “while having a positive impact on society.” Check out more of Daku’s work on Instagram.

Street art began with names, letters and symbols scrawled on public surfaces, and those markings have become more and more complex over time. Today, artists explore the beauty of lettering itself, bringing typography into the streets in fresh and unexpected ways, from complex calligraphy to words written in string and tape.

Typography String & Grass Art by Sean Martindale

Multimedia artist Sean Martindale brings text to the city in at least two highly unusual ways: with his string art installation, ‘FREE’, and ‘PARK’, a grass installation at a bare construction site.

Of the latter, Martindale says, “For some time now, the spot in has been relatively empty aside from mud, waste and strewn garbage. There’s an application to build condos on the site. It has remained undisturbed since Monday and I watered it yesterday because there hasn’t been any rain lately… Grass is pretty resilient, so it should survive and take root unless/until somebody removes it. Joe Clement assisted me with the install”

Bold Letters by Eine

Big, bold letters are artist Eine’s M.O. Known for painting them on shutters all over the world, Eine expresses his love for letters in nearly all of his works, including those he does on canvas for gallery exhibits. According to Time Out London, “His shutter pieces developed out of a mistake: he ran out of room while painting his name and realised that single letters raised fascinating questions: ‘Why? Who? What does it mean? Is it an advert?’ He takes pleasure in that lack of clarity, using his super-sized alphabet to trace a personal, interpretative trajectory across the city.”

“By the Time You Read This” by Above

This cheeky message on a wall in Guatemala City refers to the artist’s hyperactive travel schedule. ‘Above’ explains that he completed the work in two hours in between having three beers with his local Guatemalan friends.

Calligraffiti by Greg Papagrigoriou

Artist Greg Papagrigoriou approaches graffiti in a familiar, yet fresh and unexpected way: instead of the traditional form of tagging, Papagrigoriou takes a calligraphic approach. From Graffuturism: “My experience with wall painting started about a year ago but somehow I was always attracted to graffiti. Within this framework, calligraphy provided the best opportunity for me to start bringing my ideas to practice and this is how I ended up combining the three, i.e. typography, calligraphy and wall painting. The letters on the wall I make are not intended to pass a message but they function as decorative elements – patterns on my compositions.”

Urban artist SpY, from Madrid, loves to confuse people with surreal and unexpected imagery like sky-high basketball hoops and ‘Don’t Walk’ LED pedestrian symbols that escape from their confines. One such project was these stacked letters, made of bricks.

Billboard Typography by Robert Montgomery

Taking over billboards and other public spaces, Robert Montgomery’s thoughtful typographic art brings surprisingly poignant messages to urban spaces. One reads, “The flood will lift the ghosts from the Hollywood Lawn Cemetery and they will disappear like ether in the new dead air. All the names will be erased from the billboards and the theaters and the piers and the magazines and the monuments. You live by myths of immortality, and your myths are not safe.”
