It is not often that an article on the topic of illusion and deception makes it into a chemical journal. Such is addressed (DOI: 10.1002/anie.201102210) in no less an eminent journal than Angew Chemie. The illusion (or deception if you will) actually goes to the heart of how we represent three-dimensional molecules in two dimensions, and the meanings that may be subverted by doing so. A it happens, it is also a recurring theme of this particular blog, which is the need to present chemistry with data for all three dimensions fully intact (hence the Click for 3D captions which often appear profusely here).
