The Balance

The Balance is a beautiful visual representation of two sound waves colliding. The video created by Lithuanian artist Rimantas Lukavicius, shows us the sound traveling trough air, a thing we will never be able to see.

There is no explanation to be found on how the video was made, and if an analysis of the actual sound we hear was used as input. I guess it is just the aesthetics that count, this time.

Hello World! by Christopher Baker

Hello World is an audio and video installation with the subtitle 'How I Learned to Stop Listening and Love the Noise'. Christopher Baker shows us an immense amount of personal video diaries played back at the same time, creating a cacophony of voices, sharing their secrets with an imagined massive audience.

The installation is "a meditation on the contemporary plight of democratic, participative media and the fundamental human desire to be heard". There is no way we can listen to every single person. I love the way the multi-channel sound composition sometimes focuses on individual speakers and sometimes plays everything at the same time, creating an immersive swarm of voices around the visitor.
