What To do with Half Cups

So I found these half cups in my studio. As usual, I thought "What was I going to do with these?" So  this piece just evolved from what I had on hand. Size is 14.5" x 20.5" It is made of mirror glass, stained glass, smalti, jewelry bits, Italian cabescons and wire. Has taken me 3 months to complete as I worked on it when other projects percolated.
