For my parents 50th anniversary, they have it up on their wall and it looks quite stunning. Each segment of the spiral painted by different members of the extended family. Starting at the center with my baby niece and her green smudge. And then the sequence builds up by age.

Equally colorful, this one was made by the immediate family on a day when everyone was at home recovering from the flu. Each of us hid our age in our assigned quadrant.
