I feel this piece is an apt metaphor for that description. 2 halves, similar yet with distinct differences, relating to each other but retaining their own identities. Note in the detail photo that the pierced lines on one half are curved, on the other half more straight and jagged. The steel balls separate the 2 halves but also join them together. (Hidden magnets hold the 2 halves and the balls in place.)
The next photo shows the pierced edge detail.
