Using specialized diffraction gratings, a laser, and a few lines of code, he explores a unique way of projecting hologram-like images on his path to the chocolate hologram. There’s a lot of ...

A laser pointer shining on a diffraction grating or CD creates a series of diffraction spots depending on the spacing of the lines or pits in the grating or CD and the wavelength emitted by the laser.

Here I am using the exact same diffraction grating with the same camera. The only difference is that I pointed the IR remote directly at the camera (for the laser pointers, I made a dot on a screen).
