Did anyone else click and zoom for fun moiré effect?

The image shows a moire effect captured on camera, but also produces another moire effect on top at certain zoom levels

Kind of an oversimplification here: Moiré is a form of interference pattern, in this case the "grid" of OP's image has a different pitch from the grid on your phone or computer display. By continuously changing the zoom (in contrast to discontinuously), the interference pattern shifts to create "peaks and valleys." Here's some more info: https://en.wikipedia.org/wiki/Moir%C3%A9_pattern
