Toward the goal of achieving broadband and omnidirectional invisibility, we propose a method for practical invisibility cloaking. We call this "digital cloaking," where space, angle, spectrum, and phase are discretized. Experimentally, we demonstrate a two-dimensional (2D) planar, ray optics, digital cloak by using lenticular lenses, similar to "integral imaging" for three-dimensional (3D) displays. Theoretically, this can be extended to a good approximation of an "ideal" 3D cloak. With continuing improvements in commercial digital technology, the resolution limitations of a digital cloak can be minimized.
