for this animation I used two cellfractured objects and transformed one into the other

For this animation I used two animation node trees. The first one animates the shards of the cube, the second one is responsible for the sphere shards. The nodes networks might look a bit complicated but the principle behind it is simple. The cube shards get translated outward, are rotated by a random amount and then scaled to zero. At the same time the shards of the sphere make the same movements in reverse.
to achieve the washed out look I rendered the freestyle lines on a separate renderlayer - blurred the image in the compositor and then used an alpha-over node to add the lines.
