So, here's who I can thank!
Ron Fox, tileman--for a lot of pieces of light colored tile (most of the expanse). Thank you so much--I owe you!
Belva--colored and dark tile odds and ends.
Tegan and Bailey--pebbles from their beaches that I picked up while visiting.
Brigham--the use of 30 brass bullet casings.
Jill--some of her mom's necklace beads/faux pearls.
Sarah's Treasures--beads and some colorful plates that I hammered to pieces.
My garage--various metal pieces that will probably rust later and spoil things.
Home Depot, Manhattan--mortar and grout.
