We report the generation of large coherent vortices via inverse energy cascade in Faraday wave driven
turbulence. The motion of floaters in the Faraday waves is three dimensional, but its horizontal velocity
fluctuations show unexpected similarity with two-dimensional turbulence. The inverse cascade is detected
by measuring frequency spectra of the Lagrangian velocity, and it is confirmed by computing the third
moment of the horizontal velocity fluctuations. This is observed in deep water in a broad range of
wavelengths and vertical accelerations. The results broaden the scope of recent findings on Faraday waves
in thin layers
