Simon Carroll's head throwing video

It was the singular phrase 'head throwing video' that piqued my curiosity. I'd received a potter's association newsletter advertising a talk by British ceramist Simon Carroll at the Newcastle Regional Art Gallery. It mentioned an entertaining head throwing video on the artist's web site: www. simoncarroll.net. Three such disparate words that one doesn't expect to see in the one sentence: 'head' 'throwing' and 'video'. How was it possible for me to remain indifferent? I contacted the gallery and went along to his talk.
