It was during this time in New York in the late 1950s–1960s that Forakis emerged as a prominent member of the art world, and, along with artists Mark di Suvero, Edwin Ruda, Dean Fleming, Robert Grosvenor, Anthony Magar, Tamara Melcher, Forrest “Frosty” Myers, David Novros, and Leo Valledor, he founded the Park Place Gallery (1963–1967), a unique artists’ co-op space.
[citation needed] Forakis was a ceaseless experimenter and was conducting his own research during the Park Place Gallery time period.
San Francisco Chronicle Art critic Kenneth Baker credits Forakis as the “originator of geometry-based sculpture from the 60s”.
Since the late 1950s Peter Forakis has been a prolific producer of sculpture based on geometric shapes such as cubes, spheres, octahedrons and rhomboids.
By the early 1970s Forakis had begun experimenting with his “slots” technique, one of his signature achievements notable both as a unique language of examining geometry and for fabricating large scale works in steel without welding.
Cutting slots into steel and sliding sheets together allowed large sculptures to be assembled using only gravity and the weight of the material.
