Thanks for posting this! Very interesting! Sadly, the pdf files don't look very good on the screen of my computer. I'll now have to download the ps files & try again. At 12:07 PM 3/23/2012, Thane Plambeck wrote:

Most responses to my post have focussed on the frequency-domain, but what about the specific patterns (circles, hyperbolas, etc.) that we see in the spatial-domain? At some point these need to be explained.

In fact, even leaving aside sunflowers, I'd like to see a nice mathematical explanation of Moire patterns of the conventional kind. Has such a thing ever been written? You'd think so, but I wasn't able to find one anywhere on the web last time I checked!
