I just wanted to share this marvel. I currently use this texture pack both on and off the server, and has some of the better looking textures, in my opinion. I really like the way the minerals look in this.
Misa's Realism Texture Pack (http://www.planetminecraft.com/texture_pack/misas-realistic-texture-pack/)
NOTE: MCPatcher required for this texture pack
The ores look so real :o
A really good tp overall.
