Created by Technical Earth (Mo H. Zareei + Jim Murphy), interference [dac] is an audiovisual installation that explores the combination and interaction of waveforms in one medium with those of another. In the installation, which includes a linear array of four miniature projectors  affixed to loudspeaker cones, sound waves affect light waves while analogue elements alter digital ones.

Created by Marcos Alonso, Samplr lets you make music and play with sound in a new and intuitive way by touching the waveform on the screen directly with your fingers.
