First off, UF stands for Un-Finished. Either way it sounds kind of cool. I made use of the animation update for minecraft 1.5 and edited some of the colors for grass and such. I wanted this finished before uploading it, but its an interesting pack so I had to share it with all of you. the sky part was kind of tricky to get to work, but fortunately it does! I hope that you enjoy this pack even though it is far from done.
