Take a look at these typographic artworks by Aaron Keuhn. In particular the ones detailing the body really stand out as educational as well as pleasing to the eye. However, it is the clever use of typography that make them stand out. Thanks to Kirk for highlighting his work.
Aaron Kuehn composes typographic depictions of complex systems, such as the Skeleton Typogram. Using custom type tools and techniques, system–maps are articulated by modulating word-shapes with contextual meta–data.
