Ripped off rock star


If you see a wild moiré pattern, it's your screen/monitor reacting to the tiny pinholes in the image...click to enlarge and the moiré should disappear.

That's amazing! The tape and paper...they look like they are attached to my monitor and not part of the shot!! Crazy cool!

Poor mb, I feel her pain!

"Moiré" seems like a word I ought to know. Introduce us, will you? I'm just a little wary of going up to French words all by myself.

Hi all -- tired ol' LW online virtually the same time Dave is, so fresh gloss on "moiré" for y'all.

(And.."hahaha!" to Dave. I don't think there are many words that'd scare you.)

Moiré is used to describe the interference pattern formed from overlapping pattern-on-pattern.

Etymology?
Seems to have originated as a fabric term.
From the warp-and-weft web to a pixelated Web, here's a tiny tour of "moiré."

I became familiar with this use of the term during my stint in graphic arts.

From
http://www.dtp-aus.com/hlftone.htm --

"... The pattern created by 2 or 3 halftone screens layed at 30 degrees to each other is called a rose pattern, a seemingly simple and unobtrusive pattern that normally does not offend the eye. However as soon as we diverge from this ideal we start see a moiré pattern that progressively gets worse. ..."

And, since nothing exceeds like excess, here are some more moiré links:
