The Simple Act of Making a Mark
[Alan Rorie] developed The Simple Act of Making a Mark, an installation about abstracting the creative process: The machine begins by looking at what is placed before it and detects patterns within it. The machine then traces those subtle patterns, amplifying and solidifying them until generative patterns emerge autonomously.
The installation uses an Arduino Uno, an AdaFruit Motor Shield, a single USB HD web camera is used for both the computer vision and to build a time lapse movie of each loop. The software is built using Processing with Messenger, controlP5, fullscreen libraries, and v3ga blobDetection. In addition gCode command structure was used and Bresenham’s line algorithm to determine where and when the steppers should move.
