As a passionate lover of "real" art books, I've been skeptical about whether an app would ever come close. Well? "Leonardo da Vinci: Anatomy" has, and it goes further. Featuring ALL 268 pages from the show of at the Royal Collection, London, in super sharp retina display ready resolution, complete with the ability to zoom in, and translate Leonardo's famous "backwards" notations, it's a true treasure trove for art lovers, art students, as well as those in medical fields. It's a benchmark for other art book/new media publishers, and I look forward to seeing what this infant medium of art apps will produce going forward. It's so exceedingly well done that it's probably a more complete experience than an attendee to the actual show will get, which makes probably missing it in person a lot easier to take, while providing a lasting reference and ongoing learning experience.
