Crying Obsidian refers to a leaked, abandoned project by Jeb to implement a change-spawn obelisk. They appear as Obsidian blocks that look as if they are crying/bleeding . This texture was added in Beta 1.3, but was never used in the game. It closely resembles obsidian. It also appears to be a sandstone or a bedrock texture modified to look like obsidian. It is also known as "Bleeding Obsidian" among many members for its appearance instead of its official name, Crying Obsidian. The Pirate language term for obsidian is "Rock o' Tears", which is possibly a reference to Crying Obsidian.
