Black-and-white simple drawing of an Anthro dog head with droopy ears, with 3D XYZ axes (like those found in most standard 3D software) attached to his head, the axes also having rotation labels "Roll" (foward/backward axis), "Pitch" (left/right axis) and "Yaw" (up/down axis).

The same drawing above, but its axis rotations are re-labelled "Nuh." (shaking head), "Yuh." (nodding head), and "Wuh?" (tilting head).
