The Camera Map modifier (world-space version) lets you blend an object into the background throughout the course of an animation.

The Camera Map world-space modifier is similar to the Camera Map object-space modifier, in that it applies UVW mapping coordinates to the object based on a specified camera. As a result, if you assign the same map as a Screen environment to the background as you apply to the object, the object is invisible in the rendered scene.
The main difference between the two versions is that, if you move the camera or the object using the object-space version, the object becomes visible, because the UVW coordinates are fixed to the object's local coordinates. Using the world-space version, however, moving the camera or object allows the object to remain invisible because the modifier uses world coordinates instead.
