Acid Shaders

Acid Shaders is a classic and iconic shader pack by BruceKnowsHow, based on previous shader packs by Gaeel and Epocalypse.

Animal Crossing Shaders is another shader pack in similar vein, but goes for more of a spherical effect rather than a trippy one. This is somewhat similar to other curvature shaders.

Both of these may already be superseded by a newer shader pack from the same developer: Ebin Shaders

A new version, dubbed R7, was developed and released by RYRY1002. They also worked on Acid Interstate Shaders.
