What does it do?

The interactive installation emerged from a desire to challenge the rigidity of controlled public spaces and redefine urban design ideals that valorize cleanliness, order, and sterility. Rooted in the exploration of ‘loose spaces,’ the installation invites the public to recognize that even the most familiar, tightly controlled environments hold latent possibilities for urban looseness, interaction, and play by drawing inspiration from the messier, more improvised, and often demeaned public spaces of cities in the Global South. These spaces - dynamic, layered, and shaped by everyday negotiations - embody a rich potential for sociability, informality, and collective authorship. The installation is both a visual provocation and a spatial suggestion, asking: What else could this place be? In doing so, it proposes a shift in how we value and design urban space - seeing potential in the “misuse” of public domains not as failure, but as a form of participatory urbanism that can loosen and humanize even the most rigid environments in developed contexts.

 

By live-projecting movement and activity from one site into another, the installation quite literally imprinted one urban context onto another, collapsing geographical and cultural distance through spontaneous and playful interaction. This overlap allows passersby to witness how a similar urban space was being animated elsewhere, sparking curiosity and subtle comparison. It aims to challenge expectations of public space and get passersby to advocate and demand for different ways of occupying, using, and engaging with streetscapes.

The Prototype

Prototype of the Shadow Exchange installation, set up across two separate locations. Positioned horizontally with an internal light source, the setup allowed a participant’s shadow to interact in real time with the live-projected imprint of a person at the other site - creating a fleeting, shared moment across space.

The Installation Proposal

The installation captures the shadows cast by people’s everyday movements and activities along a specific sidewalk in Bangalore. These shadows are then projected in real time onto a designated sidewalk in Austin. Simultaneously, shadows cast by people on the Austin sidewalk are projected onto the Bangalore sidewalk, creating a live, cross-continental interaction.
