That's a cool effect, isn't it? You'd start with a single image, make multiple copies and apply a square mask to each one, isolating different parts of the image. Then you layer those on top of each other -- you could use a drop shadow with each, directing the shadow to move in an upward direction.... Better yet, you'd set things up in 3D space with lights casting the shadows and also helping to create those nice gradients on the images (you could also do those gradients by hand in photoshop, or using masks, the Ramp filter, etc). Finally, you animate the layers left to right.
They also have some movement happening inside the images; if you wanted that you'd precomp the image and do some animating inside it....
This is one of a half-dozen ways you could accomplish the animation. But the essence is that you're breaking an image into pieces, animating those pieces, and casting shadows.
