This subroutine first draw a circle with an epicenter of (4,4). It then has a radius of 3 followed by
random colors done with [randint(0,255), randint(0,255), randint(0,255)] this can generate a random number
from 0 to 255. For instance, it might generate [10,233,100]. The last value of 0.1 is the number of second
it will keep the image displayed.
