Daniel Palacios took a piece of string and two motors and turn them into an amazing art installation:
'Waves' utilizes a basic construction of a long piece of elastic string and two motors to visualize the presence of people close to the installation. The string between the two motorized chambers reacts to the people presence and movements, it twirls to produce a sine-wave simulation that eloquently resembles both the digitization of real-time sound waves and patterns of flow and connectivity found in natural systems.
