Break apart text or graphics into small squares?

Here’s another one. Does anyone know how the logo in this site was animated to break up into squares? Is this an old trick, something new or just plain hard work? These are the tricks you can’t find anywhere but people would love to know how the heck did they do that. Please help!

Also, check out my post about how to camera pan 360 around the stage. I’m left scraching there as well
