    Quiz 02
    § // Lava / fire texture around the space to avoid get closed to the walls
    § // Terrain at the center. Add altitude to the pain with stone texture
    § // What about making a cube able to move (rotate or something).
    // But, the terrain will not be plain (it is a non-flat surface)
