Micro Shaders Twinkle Star (Only for 1.2)
Twinkle Star (Star Flicker) is a lightweight shader for Minecraft Pocket Edition, but once you try it, you’ll never want to play without it. It introduces the effect of twinkling stars in the night sky. Look up at the stars and ponder the vast mysteries of the universe.
