How can I do this?

[Michael Szalapski]

There are several effects in the video, so I’m not sure which ones you’re asking about.

If you’re talking about the pictures flipping into place this is very easy to do; it just takes a very long time and good planning to make it look right. It could be done with layers of pictures set up in 3d space to form a wall; each one with its anchor point set to its right side. Then animate each layer’s y rotation. (I’d have each set of layers that make up each wall parented to a null so you can arrange them more easily.)
