They miss an line right at the end. I would have spend quite some time to make it look more of a pyramid as you have rather than leave away the final peace of the puzzle as they have. Though to be honest I would have not played with the text in that way to begin with.

That footer navigation looks like an after-thought, or a joke. I like the top of the page though: clean and simple.

Pretty simple. This does the trick:

body{text-align: center;}
