This project presents an interactive audiovisual installation where a digital organism reacts to the physical presence of the user. The system combines an Arduino microcontroller, an ultrasonic distance sensor, and the Processing programming environment using the P3D engine. The installation creates a deep-sea environment where a generative 3D tentacle responds to the proximity of the user by changing its movement speed and visual agitation. By integrating texture mapping and advanced 3D geometry, the creature exhibits organic behavior, bridging the gap between physical movement and digital representation.
