Jelly World Mod 1.6.4
This shader makes the world around you shake and wobble. It’s basically an earthquake of sorts, but the Jelly World name stuck. Some detail is also present in the shader; characters, grass, snow, wheat and other stuff “bounce” up and down and water splashes about like crazy.
Warning: These shaders may induce motion sickness in some people.
