This mosaic was made as an homage to my brother. After he died, my sister found a collection of large obsidian specimens amongst his things. He was a bit of a rock hound and especially enjoyed searching for arrowheads and other Native American remnants. Still, the obsidian collection was a surprise. Within the year following his death, I made this mosaic using one of the obsidian specimens.
My original idea for this mosaic was inspired by a project in a mosaic book (posted here), and I actually started this mosaic before my brother passed away. Then, it went in a bit different direction and you can read more about it here and here.
As for this in situ image, it was created using the Artrooms app. I especially like the contrasting wavy patterns of the vertical furniture and the horizontal mosaic. My brother would be very happy in a room like this!
