Moiré patterns are often an undesired artifact of images produced by various digital imaging and computer graphics techniques, for example when scanning a halftone picture or ray tracing a checkered plane (the latter being a special case of aliasing, due to undersampling a fine regular pattern).^[1] This can be overcome in texture mapping through the use of mipmapping and anisotropic filtering.

Yeah - whatever. All I know is these are just fascinating. In a low tech kinda way.
I guess the first one I ever saw was on TV - The Green Hornet, to be specific.

That was that start of a long quest.
In the 80's I got my hands on a line plotter at my work study job ... but that was a long time ago.
I knew I'd have the time to do more exploring someday.

Recently I drew this picture which reminded me that moire patterns are not about the lines - they're about sculpting the WHITE SPACE.
You almost have to un focus your eyes to get sucked inside. But they'll start moving on ya.

Here's what I came up with just three colors of straight lines at slightly different overlapping angles.
RED - GREEN - BLUE sources are at MCARRICK.COM. I'm just getting started with this stuff ...
