Eric Souther (Philosophical Tools on Patreon) just released a new Touch Designer TOX (processing module) named "PixaVex" - its reminds me a bit of a Rutt-Etra device, but can do a wide range of raster modifications including being driven by internal oscillators. It's a very cool processing network!
I took it for a spin with some archival footage from a visit (long ago) to a small startup company of a friend of mine Chuck Canon - Honeybee Robotics. Here are some examples of PixaVex at work with fairly subtle luminance 'Z' extrusion settings. [turn on audio]
