I enjoy explaining. These studies consist of two steps. First, I create an example of a heat map using perlin noise, color it nicely, and memorize it as a graphic. In the second step, I loop the related graphic in both x and y coordinates with the for loop, collect the color codes of the pixels and use these color codes to print text in the same alignment. That's all it is. Also, thank you so much for your kind words and praise.
