It's free.

A few interesting links

The League of Moveable Type create beautiful, free and open source, @font-face ready fonts. Can do nothing but be in awe and respect these guys. Nice website as well.

Basic Maths seems to be a complex but beautiful and definitely working WordPress theme based on the Grid layout. Even if you are not going to buy it, I think it serves a few very interesting ideas. Inspire yourself!

Stacey CMS is something I should look closer.
