What are some unique ways to display urns at home?

As I am in my late 70's, I've decided it would be a good idea to make some of my funeral arrangements myself to lighten the load on my sons. I've already decided that I want to be cremated, and I've even found the perfect urns to keep my ashes in. I want my three boys to each have their own urn and to keep them in their homes so a piece of me can still be part of their families. What are some unique and creative ways they can display the urns in their homes? I'm asking because I don't want to be forgotten about at the back of a wardrobe or stored in the attic. Thanks for sharing your ideas.
