OP art never seemed to get its due. An alter history to Minimalism. To which Op art was anathema, a reliance on our immanent biology instead of grand truth, axiomatic objects, specific objects. Op art was fucked up in comparison. Slippery, psychedelic, subjective. But with the current legitimation of psychedelia like the neosurrealism before it, we can expect the retroactive rise of its forebears.
