The visual centerpiece of Pulse is an anatomically-correct heart, beating fire through its four chambers to emulate the blood flow through the human heart. The outer steel structure is formed by the intricate vasculature and predominant veins and arteries of the heart. Above the heart chambers, the aortic arch shoots spectacular pulses of fire into the night sky.
Using biosensors, participants can synchronize the beating of Pulse with their own heartbeats. Participants also control the bursts of fire from the aortic arch using buttons and valves.
Surrounding the sculpture are two “Pulse Pods” which allow space for people to gather, sheltered from the sun by day and the wind by night. The pod design is inspired by lungs, and multicolored alveoli-shaped bulbs light the interior of the pod. Interactivity allows participants to fill each pod chamber with the sound and vibration of their own heartbeats.
Near the pods, emerging from the ground around Pulse are veins and arteries with hypnotic, spinning vortices of red and blue flame, providing ambient heat for cold nights.
