Not only does a video make sense to show what the book contains, it's a killer way to market such a product. The title won't be released by its publisher, Roaring Brook Press, until October, 2008—seven months away. And yet this clip can now be found not only on the usual suspects, such as YouTube and DailyMotion, but on just about every design blog in the universe. And now here.

Was this too soon for such an initiative, given the distant release date? Perhaps not, since the wily publisher has already made the book available for pre-order on Amazon, where its sales rank indicates that it's doing very respectably. The only thing missing is a dedicated web site to tell prospective purchasers more about it.
