You will notice references to Connie in this, that's because she was the
original image I tried with this code. You will need a 400x239 PNG image
called asky.png for this code to work unamended. And yes, you will Mega-POV
to do this.

PS. The clock stuff is in there, again, because of the original Connie
animation I did.
