This is oddly adorable. Not sure about putting your grandmother's ashes in there, but a loving partner would be oddly intimate.
"21 Grams is a memory-box that allows a widow to go back
to the intimate memories of a lost beloved one.
After a passing, the missing of intimacy with that person
is only one aspect of the pain and grieve.
This forms the base for 21 Grams. The urn offers the possibility
to conserve 21 grams of ashes of the diseased and displays
an immortal desire.
By bringing different nostalgic moments together like
the scent of his perfume, ‘their’ music and
reviving the moment he gave her her first ring, it
opens a window to go back to moments of love and intimacy.
She is able to have an intimate night with her sweetheart again.
The cabinet functions also as an acoustic amplifier.
In the back of the cabinet there is room for an iPhone,
the music plays their music through the ‘forget me not’ flowers
on the inside of the cabinet. The key to this cabinet
is also a golden collier.
So that she is the only one who can access the cabinet.
21 Grams is not only a way to tempt a person to revive an
intimate night with her love again
but also displays an accusation against
the unavoidable passing of life."
