Realistic proximity voice chat for Simple Voice Chat: voices fade with distance, are muffled by walls (occlusion), come through doors and echo in caves. HUD, presets and sound zones; server-side walls work even for players without the mod.
Animated GUI themes for every screen: Halloween, Hologram, Winter/Christmas, Space and Retro Arcade. Chest panels rise out of the chest, frames glow, furnaces burn. Items keep their real colours. Client-side.
This mod adds a new level of danger to Minecraft in deep caves (below the Y=0 level). The deeper you go down, the stronger the curse will be when you try to climb up.
