Ever wanted to have a sky that looked like you were on the surface of the moon? In this pack even when it's day time the sky looks like night because on the moon there is no atmosphere! It looks really cool and really makes it feel like you're on the surface of the moon!
Note: Requires Optifine! Also, recent changes in optifine break older versions of custom skies. I have included the universal pack which will work with "ANY" version of Optifine or Minecraft.
