PING

Ping is the first collaborative work by Rebekah Wostrel and Ted Coffey. We wanted to combine ceramics and technology to make something that looks beautiful, involves people and makes beautiful sounds.

To achieve this, each of the paper porcelain cones you see has a light sensor in it (called ‘photocells’ or ‘photoresistors’); they measure how much light falls on them. They take turns sending these measurements a few times per second to a dedicated microchip, where they are converted into MIDI (‘Musical Instrument Digital Interface’) data. That data is sent to an Apple laptop, where friendly sounds are made in the Max/MSP music programming language and placed in a stereo field. When a person moves his/her hands above the surface of the dome, a stream of computer generated sound correlated to this movement issues from two loudspeakers. The sounds vary in timbre, volume and position in the stereo field, according to the speed of the hand and its distance from the cones. Each audient therefore creates his/her own individual, real-time composition.
