Diffraction grating is an optical grating with a periodic structure that diffracts light, or another type of electromagnetic radiation, into several beams traveling in different directions (i.e., different diffraction angles). The emerging coloration is a form of structural coloration. A diffraction grating can create "rainbow" colours when it is illuminated by a wide-spectrum (e.g., continuous) light source.
Hologram is a recording of an interference pattern that can reproduce a 3D light field using diffraction.
Here is iPhone's home screen without and with a diffraction grating glass.
Here is a front view of iPhone's blank screen, looked through a diffraction grating glass.
Here is a side view of iPhone's blank screen, looked through a diffraction grating glass. Ghost images floating above and below in the air make 3-dimensional hologram.
