"Feeling lost in his songwriting process led Grammy-nominated artist j.viewz to the refrain ‘Almost forgot the heart.’ For the lead single from his new album 401 Days, we created a digital experience that would help us feel fully in the moment—the very thing that j.viewz had struggled with. To create a music video completely controlled by the viewer’s own heart, we created an algorithm that would detect the slight changes in skin color that occur each time your heart pumps blood through your body—a process known as photoplethysmography—and then would adjust the song’s tempo and visuals to fluctuate in sync with your heartbeat. By placing your finger on the back of your device, you see a small creature traveling through a landscape that becomes increasingly colorful the longer you stay present.”
