A basic element is arranged into an 8x8 grid structure, where every other one is hidden. The size of each square is determined by the wave-shaped sine-function. The functions sine and stretch are supposed to make the code easier to read. Sine converts angles from degrees to radians, and calculates the sine. Stretch scales and shifts the sine values, which are somewhere between -1 and 1.
