It is a section by section look at the Catechism, in bloggy-awesome-goodness.
In all seriousness, Stephen is an intelligent mind, and has a keen attention to detail. I am excited for his project, as it gives me an opportunity to read through the Catechism with the insight of a person I respect and who entered the Church around the same time I did. (I can tell he is already light years ahead of me!)
Take a few minutes and go check it out, and let him know that I sent you!
