content: With pictures all over the CD I was led to believe that at least minimal effort would have gone into including at least some of the illustrations from Leonardo Da Vinci's notebooks. Not one illustration is included on the CD let alone the complete works. :( While having the footnotes is potentially useful for scholars, having the illustrations would have been far better.The product description needs to be re-written to include the fact that this is a text only presentation and thus not as complete as the title leads one to believe. In fact, the title should be properly revised as well because it is deceptive.
