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.
