This is a 90 minute talk by Fraser Armstrong of Oxford University (http://armstrong.chem.ox.ac.uk) explaining the electrochemistry of proteins immobilized on surfaces.  The talk was presented at the 3rd Bioinorganic Workshop in 2014 at Pennsylvania State University.  The talk contains an excellent basic tutorial on simple electron transfer on immobilized substrates using simple iron sulfur proteins as the primary example.

Introducing you to 3DMolSym:  A Web Resource for Teaching Molecular Symmetry that uses Adobe Shockwave for Visualizations and Animations.

Note there is a slight difference when operating this resource on a Mac or in a Windows Operating Systerm.  On a Mac if you don't change an item (any item) in the pull down menu on the right when the resouce opens, the selection of molecules will be frame shifted by one molecule.  An easy fix is described in the Description below.

I have provided a link to a Web Resource:  The Strucutre and Symmetry of Metal Tris Chelates which I developed several years ago with my collegue Henry Rzepa from Imperial College London (and which was posted as Web Ware on the Jourmal of Chemical Education Website and is not longer available to view there).  The Web site uses 3D images of known molecules and scripted commands to teach about the symmetry elements and operations in these molecules.  Instruction is also given on assigning absolute configurations and ligand twist conformations.  Animations of the Bailar Twist and Ray Dutt Mech

The Sheffield Chemputer is a site that does a variety of calculations including: isotope patterns, element percentages, reaction yields, oxidation states (for transition metal complexes), electron accounting (for metal complexes), VSEPR shape and classification using the CBC method. At the initial point of this post (April 29, 2014) parts of the site are still under development, but it seems to be off to a good start.

    Every day when I teach Inorganic Chemistry (and in most of my problem sets and take home exams) I create Web pages to show 3D images of selected molecules to my students.  I am a visual learner and I find the structures beautiful and informative.

    In the past few months, you likely have found that web sites scripted with Jmol scripts calling a Jmol applet (which is a Java applet) are blocked. 

Two excellent video presentations on symmetry. The Ted Talk by Marcus du Sautoy is an excellent introduction to the concept of symmetry and systematically describing it. In "Impossible Crystals" Nobel Laureate and physicist Paul Steinhardt discusses the creation of "Impossible crystals": quasi-crystals with five-fold symmetry previously believed impossible.
