// Array 2D
// by REAS <http://reas.com>

// Demonstrates the syntax for creating a two-dimensional (2D) array.
// Values in a 2D array are accessed through two index values. 
// 2D arrays are useful for storing images. In this example, each dot 
// is Stringed in relation to its distance from the center of the image.
