The excellent efforts of a certain DAVID BRINDLEY, looks at the art of cremation (wait, come back!) and the unusual things people do with the ashes of their loved ones. We are introduced to Helen, who keeps the remains of her husband in a plastic Chinese takeaway box, with "STEVE" written on the lid in marker pen. Helen's plan was to put his ashes into 50 shotgun cartridges and have him fired into the sky by his friends. She also turned (some of) him into a diamond. To accomplish this, she had to post him off in a Jiffy bag, leading to an unusual scene at the Post Office when the clerk asks about the package's value.
In addition, you could watch this 3 minute wonder, originally aired on channel 4 in 2006. It touches on the general concept, but David Brindley takes a very fresh approach in comparison, so don't be put off.
