Life Imitates Op Art

Spencer L Smith & Ikuko T Smith

“Moiré interference occurs when two periodic structures are superimposed such that a new spatial structure emerges, an effect that is exploited in the works of op artists such as Carlos Cruz-Diez and Ludwig Wilding. In this issue, Paik and Ringach1 demonstrate how moiré interference can account for the architecture of orientation maps . The underlying periodic structures are the evenly spaced mosaics of ON and OFF retinal ganglion cells, and the orientation map is a result of the relative positions of these two superimposed mosaics.”
