from turtle import *
from superturtle.animation import animate

# define 3 objects
# sky, ground, sun

# In the actual animation, the sun will start off entirely below the horizon,
# (where the sky meets the ground), hidden by the ground, and will slowly rise (move up the screen),
# with the sun, sky, and ground changing color. The disk of the sun will
# be apparent only in the sky, as it rises. The elapsed_time will be linked to the
# animation frames. I will be using color shading techniques in the animation.
