*## Draw a 10x10 square using the sampled pixel's color at ever 10th (x,y)
 
*## You should display both the original image and its mosaic
 
*# Pointilism Animation
 
*## This will be an animation
 
*## Within setup(), load an image, load its pixels, and turn off line strokes
 
*## Within draw(), generate a random index number from 0 to image's pixel length (use [https://processing.org/reference/random_.html random()])
 
*##* int rand = (int) random(0, img.pixels.length);
 
*## Sample the color of the pixel from the random index and fill with the color
 
*## Calculate the appropriate (x,y) from the random index (Hint: use modulus (%) for x and division (/) for y)
 
*## Draw the circle at its appropriate (x,y) using a random diameter from (5, 15)
