Mysterious things go pop in the night

I was given a wonderful windscreen from a station wagon to use as crackle glass in some upcoming mosaic art.
Today we awoke to find the screen has toppled itself over and produced the glass babies!

I wanted to video the process but the glass was obviously dying to get into the mosaic mural I am making today, so shattered itself.

This is really wonderful, the glass knows ahead how to perform!
A mosaic miracle!
