Editing 1814: Color Pattern

The comic references {{w|moiré pattern}}s in a parody of the song “{{w|That's Amore}}” made famous by {{w|Dean Martin}} [https://www.youtube.com/watch?v=RnoDb0bMQuk in 1953]. (See [[#Trivia|trivia]] for pronunciation).

In mathematics, physics, and art, moiré patterns or moiré fringes are a kind of {{w|aliasing}} -- large scale interference patterns that can be produced when an opaque ruled pattern with transparent gaps is overlaid on another similar pattern. For the moiré interference pattern to appear, the two patterns must not be completely identical in that they must be displaced, rotated, etc., or have different but similar pitch. Moiré patterns appear in many different situations. In printing, the printed pattern of dots can negatively interfere with the image. In television and digital photography, a pattern on an object being photographed can interfere with the shape of the light sensors to generate unwanted {{w|artifact (error)|artifacts}}.

In digital photography or videography, moiré patterns occur when the pattern of pixels on the image sensor are not 100% identically aligned with patterns on the subject being photographed.  Photographs of a digital screen taken with a digital camera often exhibit moiré patterns, since it is very difficult to align the camera sensor's grid with the screen's pixel grid perfectly.  This is the problem [[Cueball]] ran into, where the photo he just took of his computer screen is covered in weird rainbow patterns (the color patterns from the title).  It is possible to reduce this effect by changing the distance and angle between the camera and the screen.  There can also be bands of uneven brightness on digital photos or videos of electronic displays, those are caused by scan lines and are different from the moiré patterns described in this comic.

[[Megan]] responds to Cueball's complaint with a song that explains moiré patterns. Her song is a parody of the song ''That's Amore'', where "Amore" means "love" in Italian. The pun is that "That's a Moiré" and "That's Amore" are phonetically [[#Trivia|quite similar]]. The title text continues the song with a second verse, again with musical notes indicating that it should be sung. More information on when moiré patterns occur is given here, indicating that the space between the grid lines should be small and the two grids should be almost identical, for the maximum moiré effect. This verse, however, could also work if ''a moiré'' was changed to ''amore'', as two people squeezed tight together, and without much difference between them could lead to a romantic relationship.

 

Randall was not the first to spoof this song using "a moiré" instead of "Amore". His two verse version, two verses from the original song, and other prior versions can be found [[#The songs|below]].

 

 

It turns out that Randall was not the first to spot the possibility of changing the lyrics from "That’s Amore" to "That's a Moiré." Verses are shown below as follows: the lyrics first to the original song, then to Randall's song from this comic, and below that other songs (with citations).

 

 

 

 

 

 

 

 

 

'''Jamie Zawinski''' and '''Michael Bayne''' wrote a similar verse for the [https://www.jwz.org/xscreensaver/screenshots/ Moiré screensaver] they made in 1997 (search for ''that's'' to find it on the linked page):

:[Cueball holds up his smartphone in front of his laptop which stands in front of him on a desk. Megan is sitting in an armchair reading, facing away from Cueball. She is singing her reply, as indicated with four double musical notes around her two lines of text.]

:Megan: ''When a grid's misaligned with another behind''

:Megan: ''That's a moiré...''
