There is a new way, however, to spectacularly dispose of the ashes. A Sydney company ( I'm sure the service would be available in other cities) offers a new type of service where the ashes are mixed with gunpowder and then fashioned into fireworks. The website states it's mission is to "help find closure by way of scattering their cremated ashes high into the sky as part of a spectacular and memorable fireworks display." They also offer a cheaper pet service as well.
I wonder if this is the 21st centuries version of the the ostentatious cemetery statue, but fittingly for our times it will only last for a few minutes rather than a few centuries.
