This is a small version that will show in high definition in full screen (but makes a nice thumbnail to indicate the presence of a video). 

This is a larger version for viewing directly on the page (also available to full screen).



Note that these videos will only play from this site... even if you know how to copy the codes from the HTML page, the provider will only render them when invoked from here (thus providing some control over where they are displayed).  A choice like YouTube would be preferred for videos which we want to be widely distributed and displayed by anyone.

Different services provide different options.  The service below is also a contender, but the free versions don't allow me to remove ads (actually they granted me a view without ads), demonstrate...
