I wonder if you realise just how much work there is involved in creating an image like this? There are lots of images like this, and I expect that you cannot find it on Google because the technique isn't usually called 'exploding'. Pesonally I don't find this one particularly pleasing, the technique has been applied well enough, but if your face was doing that wouldn't you show just a little emotion?
You can find a tutorial at
http://www.photoshoptopsecret.com/ under the 'breaking apart' title, unfortunately you'll have to pay for that. I'm pretty sure that this is done in the same way.
