“Pulse Garden” is an interactive installation composed of four thousand LED-filament polycarbonate light bulbs, each of which glimmers to the rhythm of the pulse of a different previous participant. Located in the “valley” of the Museum of Modern Art’s Sculpture Garden, the work records visitors’ heartbeats using optical pulse sensors (PPG) distributed throughout the space. Each new pulse recording is looped and replaces the oldest one, generating a continuously evolving choreography of light. The installation also reproduces the sound of each heartbeat, creating an intimate and complex soundscape. As visitors move through the installation, they encounter a biometric concert composed of the pulse recordings of the last four thousand participants.

This work belongs to a series of Pulse artworks that Lozano-Hemmer has been developing since 2006. Like others in the series, it was inspired by a scene from the film Macario (1960), directed by Roberto Gavaldón, in which the protagonist experiences a hunger-induced hallucination where each person appears as a fragile candle burning in the caves of Cacahuamilpa. Pulse Garden is a meditation on the transience of life: each rhythm is singular, ephemeral, and ultimately replaced by the next. Like a contemporary memento mori, the work does not admonish with gravity but with longing, reminding us that everything that lives beats, and everything that beats will pass.
