"Library for iPhone" by Jessie Char and Maja Henderson
And speaking of incredible iPhone app demos, please appreciate the love and detail that went into this fantastically cute and clever video promo for Delicious Library's iPhone app. Jessie and Maja thought to do what no one else has - to swede an iPhone interface. Bonus points for Scott Joplin. Extra double-score bonus points for YLNT and Sandwich Dynamics references in the Mac interface.
