The M Machine Live Video Mix
“The M Machine Live Video Mix” is a project built with TouchDesigner, featured in the Derivative community showcase in 2013.
"Using TouchDesigner, a real-time node-based 3D and visual composition software, we created a virtual "M" that can represent the sequenced light patterns exactly as our physical "M" can, with the added ability to display video on the face of the "M".
