Camera mapping
Both in the past as well as present there has often been queries of how to do camera mapping. The idea of this type of mapping is to take the texture from projection through a camera rather that local mapping. This is often need for VFX shots. Shots like the object seeming to come out of backgrounds and more often for effects like talking animals etc… We are going to use much simpler objects to show this example.
Create a camera or use the persp camera and create an image plane

The same image as that of our image plane and render this
We can notice the background sort of distorted, as the mapping on the object does not match the image in that of the camera plane. Now we need to tell the object has to get not the planer mapping but mapping from the camera. Selct the projection mapping from the hypergraph menu

Once this is done, more often we'd want to bake the texture on to the object.

We can then animate the object to come out of the screen or morph to another shape
In the similar way we can make some nice effects … For example From a Grumpy toad
To a Toad with a bit of smile

On similar process we can create various expressions as well as talking animals/objects.
