This article is a work in progress, but serves as a log and journal as the author explores the TouchDesigner software and framework. This author began learning TouchDesigner in the Fall of 2019.
TouchDesigner is a node based visual programming language for real time interactive multimedia content, developed by the Toronto-based company Derivative

Bruno Imbrizi‘s tutorial on how to create a network that simulates just one of many effects the Rutt-Ettra Video synthesizer produced in the 1970’s. In this tutorial video rasters are simulated with a grid chop that is uses colors and luniance values to offset the incoming media on a z-plane.
This is also a good introduction to touchDesiners’s GLHS MAT’s and scripting. Be sure to follow up with part 2 to add additional interactivity with controls such as buttons and sliders.
Mathew Ragan does a good job of deconstructing and recreating the Rutt-Etra Video Synthesizer in a TouchDesiner network patch that you can build and use to render out video. In short :
“This particular technique is perhaps most well known to us because of the Rutt Etra Video Synthesizer. This video synth was an attempt to begin manipulating video in same manner as sound was being manipulated in the 1970s, and was truly a ground breaking examination of our relationship to video – live video especially. One of the most famous elements of the Rutt Etra Synth was z displacement, the change in the depth of an image based on its luminance.”
Here’s a rendered out example:
