With dramatically bowed edges, coiled shapes, and fragments jutting in opposite directions, Instruments by Rick Salafia defies many standards of measurement. The ongoing series, which currently comprises more than 200 works, disregards the one-foot rectangle in favor of a playfully diverse array of shapes. Semi-circles stretch like a croissant, ends expand into wide, asymmetric forms, and a segment stretching just a few inches breaks free from the rest of the metal tool. While the pieces in Instruments take on impractical shapes and proportions, the individual inked lines and numbers remain relatively uniform, evoking the systemized nature of a typical ruler.

Salafia produced each work in an edition of three and has some available in his shop. You can find more from the series on his site.
