I used HyperChem in my first venture in biomolecular visualization and computation. I eventually made some tutorials in which information was passed between HyperChem and Toolbook. When I became aware of Chime, I focused most of my work on protein structure and function and used Protein Explorer and PiPEs as they became available. When MolSlides became a feature of PE, I developed an assignment for biochemistry students to make MolSlides of a protein of their choice. In the early years of this work I received a variety of internal grants from Messiah College, and in more recent years I have been receiving release time from teaching. Realizing that Chime was on its death bed I got serious about learning Jmol during the Summer '07 , and during my Fall '07 sabbatical I ported most of the PiPEs to Jmol and converted the last of the HyperChem scripts to Jmol scripts. For most of this work I used α and β versions of Jmol Tutorial-Authoring Template being made by Eric Martz. My first exposure to Proteopedia was mentoring Emily Forschler as she developed Photosystem II.
