Advent Stained Glass Mosaic, part 1

The first Advent Mosaic from one of Holy Trinity's, and Anselm Society's, artists, Lisa Eisenhardt.

Lisa's accompanying text:

I have not practiced the season of Advent throughout my life; it’s new to me so I wanted to experience it through my mosaic art. The process of making the mosaic itself is relevant when I think of Advent. Every piece that is broken, shaped, and placed on the substrate is sacred, just like the hurting and ugliness in our lives. When I begin the process I don’t know what it is going to look like at the end, I fully submit to God for the outcome. Trusting in the process is the only way I continue on sometimes because the mosaic can look so disjointed and ugly before completion.
 Different moods emerge from the piece as it filters changing light throughout the day.

The seeming lack of continuity and cohesiveness in the piece at this stage reminds me how unfinished I am. And so I continue plodding through, remembering all the while what God has done for me in the past. The faith in the process keeps me moving on to the next step.
Many questions and truths about hope are found in the dark. As you examine and ponder your own inner life, I encourage and desire for you to extract your own meaning from the first piece in a series of five called “God with us with God”.
Notice the “movement” in the entirety of the mosaic. How does that impact you and what meaning and truths might be available through it?

What scripture, poetry, or literature comes to mind? 
What do you feel and think about when you see the opaque black glass? Light doesn’t go through those pieces, but reflects it at times. 
And what is that little spikey thing???
I invite comments and questions.
