The 1984 work Signal is a later, refined iteration of Takis's Signaux series, blending his kinetic roots with structural monumentality. Romantically aligned with nature and spirituality, it's an iron sculpture designed to move and resonate—echoing the cosmos within its simple form. Within Takis’s practice, this piece sits at the convergence of his early experimental Signals and his later sculptural mastery—both echoing his ambition to materialize unseen energies and foster sensory dialogue between viewer, nature, and the spiritual dimension.
