WOAH! If you look at the computer screen, there are beautiful mathematical curves there. If anyone with the knowledge on why the curves look the way they do and their color, it would be very appreciated. I am very curious right now laugh.

The color patterns you are seeing are known as moiré fringes. The image posted here is not a screen-shot; it was created using a digital camera to photograph a computer screen.

 

Moiré fringes occur when the photo sensor (a dot matrix array) focuses without alignment on a computer screen (another dot matrix array), any misalignment in the matrixes will cause interference patterns.  A similar moiré effect (with less color) is noted in photos of near-focus objects imaged through a (window) screen. 

 

The moiré fringe artifacts disappear at zero degrees (alignment) and at multiples of 30-degree angle rotations. This is easily observed by rotating the digital camera while viewing the image in the video monitor.
