After some experimentation I have managed to get a short extract of the 'Cowboys' video onto my website here. It may take a moment or two to start, but it had to be a reasonable size to eliminate undesirable side-effects of video on the web. Sadly you can't get the full impact, but it does give some idea. I'll add a text later. Any feedback would be greatly appreciated.
I tried, but in the end decided to take the video off the website, simply because the limitations of web technology mean that it does not work as intended. The link now goes to a page containing a video still.
