As Angel said, Jmol loads the Gaussian .log fine. My recollection is that the Gaussian files contain all the steps in the optimization just like GAMESS (the package, I'm most familiar with). Once the .log file is loaded all you should have to do is turn animation on with a script command. Try "frame rewind; animation on;". If each step is in multiple files you will have to load them into frames separately, before starting the animation. In the Jmol application you can just use the animation buttons up in the tool bar, to control the animation. The development version of Jmol (12.0) will also automatically generate a web page with animation controls using the WebExport function/dialog.
