This person has built an algorithm to draw images using two channels of an oscilloscope. The two channels use addition and subtraction of analog waveforms to create the imagery. I love this piece because he takes a computational approach to render drawings. I would love to see this attached to an analog oscilloscope (one that uses a laser to illuminate phosphor powder). Within the past could years, I was exposed to the idea of creating interfering waves to control amplitude (I never took calculus). Since then, I have been fascinated with moiré patterns to create visually dynamic art and to control density of color value. This work relates because the artist is using the same principles to send interfering information to create something that is recognizable to humans. In this class, I would like to learn about generating analog wave forms from static imagery: the inverse of this artists’ work.
