Dan Sandim

"In 1973, Dan Sandin designed and built a comprehensive video instrument for artists, the Image Processor (IP), a modular, patch programmable, analog computer optimized for the manipulation of gray level information of multiple video inputs. Sandin decided that the best distribution strategy for his instrument "was to give away the plans for the IP and encourage artists to build their own copies. This gave rise to a community of artists with their own advanced video production capabilities and many shared goals and experiences." In this segment, Sandin demonstrates the routing of the camera signal through several basic modules of the IP, producing a "primitive" vocabulary of the effects specific to video." - Video Data Bank
