HEART TUBE is an interactive installation that transmits heartbeats of up to four people simultaneously to the showroom, in real-time. The sculpture explores human communication and interconnectedness through a simple biological process, focusing on the heart as an organ extremely susceptible to external stimuli and internal processes (thoughts, emotions, etc.). The heartbeat makes every physiological and psychological change instant, directly and unconsciously visible - through deviations in rhythm. These deviations are amplified and made visible through the transformation of the sound of the heart and its rhythm into light and strong, tactile vibrations. The volume and rhythm of light and sound again affect the heartbeat of the people who are connected through sculpture, which creates a "communication loop" and a kind of cyber feedback. Experimenting with the interface of technology and biological, the work speculates on the possibilities of creating new, different ways of communication and perception - those based on immediacy and uncontrolled biological processes.

Technically work consists of 4 DIY electronic contact stethoscopes. Each is connected to a separate preamplifier, mixer, amplifier, subwoofer speaker, power supply and an Arduino microcontroller that transforms sound into light pulses of varying intensity. All the devices are built into the sculpture structure made of drain pipes ( tubes ) and construction wood. The speakers are arranged vertically and activated by pressing the button on stethoscopes independently of one another. This creates a specific movement dynamic within the sculpture. The rhythms of four human hearts activate LED lamps beneath each speaker and merge into one dynamic rhythm that resonates loudly in the showroom. The color of the LED lamps changes according to the tempo of the heartbeat and changes to red if it gets faster and green if its more relaxed.
