Scratchrobot by Stijn Slabbinck

The Scratchrobot is an installation based on two turntables, a computer and a robot-arm. When an e-mail is sent to robot@spess.com , the message will be analyzed and then turned into signals that control the robot. They make it scratch a series of sounds, which are recorded and sent back to the sender of the e-mail. The spectators are invited to interact with the system by activating the robot with their personal input. Every e-mail results in a unique sound.
Scratchrobot was invented while questioning different ways of communication, its patterns and code systems. Building it was an attempt to "control" the daily info-flow in a multimedia way.

Stijn Slabbinck (1976) graduated from the Academy of Fine Arts in Ghent where he studied 3d-multimedia. Few years ago, he founded the company SPESS, which provides technical support for events, film and theater productions. Stijn Slabbinck has always been particularly interested in VJ-performances, automation and special effects, which consequently exerted great influence on his latest work.

Messa di Voce

An Audiovisual Performance & Installation for Voice and Interactive Media by Golan Levin and Zach Lieberman with Jaap Blonk and Joan La Barbara
Messa di Voce (Ital., "placing the voice") is an audiovisual performance in which the speech, shouts and songs produced by two abstract vocalists are radically augmented in real-time by custom interactive visualization software. The performance touches on themes of abstract communication, synaesthetic relationships, cartoon language, and writing and scoring systems, within the context of a sophisticated, playful, and virtuosic audiovisual narrative.
Messa di Voce lies at an intersection of human and technological performance extremes, melding the unpredictable spontaneity and extended vocal techniques of two master composer-improvisers with the latest in computer vision and speech analysis technologies. Utterly wordless, yet profoundly verbal, Messa di Voce is designed to provoke questions about the meaning and effects of speech sounds, speech acts, and the immersive environment of language.

Messa di Voce is only one of the great project of Golan Levin, you can found more great projects here.
