What is This?

I bought this years ago based on its artistic appeal.  I hung it on the wall in my kitchen and enjoyed it very much.



But what is it?  I have thought it might be a pan for individual creme caramel.  It seems rather delicate to balance if full of liquid.



The pieces are bonded together with these metal strips.  The pans are about 3 inches in diameter and 1.5 inches deep.  The volume is just under 1/4 cup.



Would you place this in a pan of water and bake your flans?  Would love to hear what you think.
