The Dirty Electronics 7-Segment Display, initially designed for Athens Video Art Festival, is a hand-held device for sound and light that uses multiple 7-segment LED decimal digit displays (like you get in old digital clocks). At the centre of each printed circuit board (PCB) there is a pseudo screen made from clusters of 7-segment displays that generates abstract patterns with corresponding sequenced sounds. The patterns are programmed or generated manually through touch control. The device also introduces the idea of composition through electronics and 4-bit binary coding. Compositionally the 7-Segment Display explores the relationship between hand-held source-point light and projected image, and how the device can be used collectively by connecting and synchronising 7-Segment Displays together to make larger composite sound and images. An element of complexity is introduced into the piece by the movement of the performers and how they hold their displays. A cluster of digits and body parts!
