Vidal was the co-founder of the arte generativo group established in 1960 with Eduardo Mac Entyre. The group’s artistic philosophy was influenced by mathematics and physics and followed the idea that the interplay of line, geometric form, and color would produce art that generates perceived motion. Arte generativo, thereby, transforms the two-dimensional plane into a space of continual movement through the optical regeneration of forms. Vidal’s style began to evolve over time and by the 1970s and 1980s, his work took on a stronger interest in the effects of light across bands of color. His once rigid geometric shapes began to take on more fluid forms, as exemplified by Comenzando lo irreconocible.
