Tessellation-like animation in after effects
The easiest way to do this is to sync the scaling and make a cross dissolve between them as you do the scaling.  You want it to fade fairly quickly as you work your way in.  One layer would be the many images in whatever arrangement you want, the other would be the overall logo.  This is also often the technique used for doing a smooth zoom in on a satellite image from a very high level to a lower level.

If you time the fades right, it isn't that noticeable as you move to progressively more detailed images because the more detailed image is starting in while it is still small enough to not be distinguishable.

To keep the sizes manageable, you may also have to do multiple images to transition through.  Don't bring one in to the timeline until the previous image is big enough that details of it will start being noticeable.  Also, be sure to remove the larger previous image from the timeline once the newer image completely covers it.
