The Ancient Greek term κῦμα (pronounced Kima) is similar to the Latin term cumulus which can be translated as “that which swells”. The Greek term can also mean wave, the physical movement on the surface of a liquid layer.
In English, wave can also mean a dynamic disturbance of a physical quantity around a position of equilibrium.
By controlling the vertical position of a number of levitating spheres, κῦμα produces a programmable areal choreography inspired by the movement of waves. The precise control of each individual module is possible thanks to the mathematical equations defining the laws that regulate the system. Each element act individually, and as part of a system.
Midway between kinetic art and digital technology, this installation sheds light on scientific disciplines that are not very well known yet permeate our daily lives: automation and control theory whose fundaments are rooted in mathematics, signal processing and computer science.
This artwork allows to introduce and explain basics of control system design and automation science which deal with the modelling, analysis, identification and control of dynamic systems. It focuses on controlling a system to comply with precise requirements such as execution time, precision and stability.
