This project was a catalog produced by gdloft PHL for The Philadelphia Design competition, sponsored by the local AIGA chapter. It looks at the idea of "book as sculpture." Using a variable printing program, each cover is a slightly different shade of color from the last one, following the pattern of ROYGBIV. Each catalog is entirely unique and yet, when they are stacked, the spines create a seamless spectrum that evokes a sculpture. The catalog print-run was limited to the same amount of entries received (576) to represent all the work of the design community.
