Observing what has been happening on the device screen has been an informative part of my enquiry and I needed to ascertain what was creating the this phenomenon. The moiré effect is a visual perception that occurs when viewing a set of lines or dots that are superimposed on another set of lines or dots, where the sets differ in relative size, angle, or spacing. I like that this effect can occur naturally or be forced deliberately, which is something I have been exploring in my practice when taking a screen shot of the phenomenon at work.
        What I find fascinating with the moiré effect is that it can degrade the quality and resolution of images. Problems occur when a screened image, such as is found in a newspaper, is directly photographed and then the photograph is reprinted in screened format. It can also occur when the image from a computer display is reproduced by photographic means and then rendered in a screened or dot-matrix format. The fine matrix of dots in the original image almost invariably conflicts with the matrix of dots in the reproduction. This generates a characteristic criss-cross pattern on the reproduced image.

It is like the pixels are fighting against each other which leads me to find out what a pixel actually is. With reference to the display device, it is the smallest controllable element of colour represented on the screen. The pixel is variable and therefore can be manipulated to take the form of a square, dot, or line. The pixel has no physical properties and operates as a logical system. The size is dependant on the set resolution of a display screen and makes me think of what a screen is actually made of? 
        Is there some physical body to the pixel if the screen is actually made of a material? LCD screens are made up of liquid crystals that are activated by eclectic current, they are controlled from a solid to a liquid state, therefore, there are physical values to the screen which display the pixel. They are ultimately controlled by a machine which is made up of glass, electronics, circuit boards all driven by a power supply.
