Arch

I am Arch. I span the thoroughfares of your video instrument with my continuous lines and splendid ornamentation. I can show you new routes! Over, atop and between your well worn paths: join, constrain, bend and split shape and form with the magic of my nonlinear processes.2-input, 5-output wideband analog logic. Binary logic can only see two colors: black and white. Analog logic processes the continuous grayscale range of your analog signal path, enabling organic combinations of video images and patternmaking elements. 1-input, 3-output full wave rectifier and frequency doubler. We love this circuit -- you can find it in the signal paths of Staircase, Shapechanger and Navigator. With an input triangle wave, you get a triangle wave at double the frequency at your output. 1-input, 2-output gamma processor. An infinitely usable function, gamma processing adjusts the brightness of mid-gray level while keeping black and white points consistent. The square function darkens grays, and the log function brightens them.
