Here’s an interesting concept from Lots Design called The Shell. Basically, it’s an eco-friendly urn created from bio-degradable pressed paper. Not only can loved-ones leave messages by writing on the outside, but there’s also a small pocket on top for personal notes and trinkets. Once placed into the ocean, the shell over time will waste away, leaving all but a memory. Plus, it looks likes the spacecraft from Flight of the Navigator. Bonus.
