Experiments with interference between two sets of parallel bézier curves. These moiré patterns are often seen as undesirable artifacts in print, video, and photography but they have many practical uses as well.
Designs with fine, parallel curves were printed on bank notes in the 1970s to complicate the creation of counterfeit currency. This wavy line aesthetic is guilloche and it acts as a monetary security feature. These lines are difficult to reproduce with scanners and printers, partly because the arrangement of light sensors and printer heads will generate interference with the guilloche designs and produce telltale moiré artifacts.
Guilloche patterns have also made their way into “Genuine Product” stickers, such as Microsoft’s “Certificate of Authenticity” stickers for Windows shown here.
Some of these experiments play on that aesthetic.
