NOVA stands for "Neatly Organized Voxel API" and is a modding abstraction layer for voxel games. This means that you can work with the functions of this API without having to bother what kind of block-based game or mod loader you are running on. It provides modders with the ability to write mods for any game or mod loader that has a NOVA - compatible wrapper for it - which will at least include Minecraft Forge on 1.7.10 and 1.8, but we also intend to support other minecraft alternatives.
