+This is a sprite/pixel editor designed to be used to create **sprite stacks**. Sprite stacks are simply 2D layers that make up a pseudo-3D object by rendering each 2D layer at a slight vertical offset, thereby creating the illusion of depth. This sprite stack can then be rotated, shaded per layer, and more.
