Effect

Signal Feedback

Feed the output back into itself for video feedback trails.

Video feedback happens when a camera points at its own monitor, spawning infinite tunnels and trailing ghost forms. Artists and musicians used it from the 1960s onward as instant generative imagery.

Digital feedback layers trail and smear without the physical loop, but the appetite is the same: recursion as spectacle.
