I notice that I seem to generate a lot of images while doing analysis, largely using Wolfram Research’s Mathematica…

so, maybe every day I should post one of those images here- an image of something I’m working on, an “Image of the Day” (IotD) or some such.

This is a “Marroquin Pattern” used by, amazingly enough, Marroquin, to study top-down perceptual phenomena. It’s an interactive Mathematica CDF, but here’s an image.

If you’d like the CDF, just let me know and you can play around with the patterns yourself.
