When cardiologist Stephen Gaeta was finishing his PhD on cardiac arrhythmias, he decided to do something more creative than just hang his diploma on the wall. He used the words of his dissertation as create an image of an anatomical heart, which he signed with a segment of his own ekg. He later redesigned the heart using an 1809 monograph on cardiology and renamed it Beat Poetry. Since then, he has continued to create images from classic scientific texts, including an eyeball, a transgenic mouse and a set of lungs (below). The lungs feature the text of the 1628 treatise Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus (An Anatomical Exercise on the Motion of the Heart and Blood in Living Beings) by William Harvey.
