This adds a fantastic sky of a purple nebula and a huge green gas giant! I wonder what the tides would be like from that thing? Oh, there are also two suns with one straight up and never moving! It looks like everything revolves around it!

 

Note: Requires Optifine! Also, recent changes in Optifine break older versions of custom skies. I have made this a universal pack which will work with "ANY" version of Optifine.
