Philosophical Tools: Slit-Scan

Philosophical Tools is a tutorial series that focuses on toolmaking, media art, and the histories/philosophies that entangle them. My goal is to weave these elements together while I share with you how to create the processes in the node-based programming environment TouchDesigner.

This episode introduces historical slit-scan photography and video works from Ralph Hocking and Steina Vasulka. Then shares how to build real-time slit-scan systems. Supporting links and additional resources in the links below.
