VanityCraft started out as a small Minecraft add-on that added uses for dirt, and lapis, but slowly it became much bigger. The current version 0.3.3 adds Biomes, new ores and blocks, new items, and in the work is are Poison mechanics, Alloy mechanics, new mobs and dimensions, and smelting overhaul.
