It seems like the widget that allowed you to embed Google Earth tours (with audio and motion) online isn’t working. We had at least one person in the county who wanted to be able to do this because they’d seen this Jimmy Buffet tour. Compared to teacher assessment and other bottomless problems this seemed pretty attractive, especially using the Buffet page as an example. I hacked off most of the extraneous parts and this seems to serve the purpose although there are a few more pits that ought to be carved off.
You should be able to download the source HTML at this page. Once you do that it’s just changing two URL strings from what they are now (http://etechplace.org/debordenave/wp-content/uploads/2013/02/Bon-Jovi-Tour_KCJ.kmz) to the URL for wherever your KMZ source file lives. The example is below in an iFrame and it will likely play automatically. My apologies for that.
