Just like nurse logs, which will have their own collection down the road, I find driftwood endlessly fascinating. While logs on the beach eventually find ways back into the food web, their journey is almost nothing like that of a downed tree in the forest, which becomes an immediate ecological facilitator.
Instead, the driftwood on the shores I frequent is slowly cured and contoured by sun, rain, sand, and salt air - accentuating grain patterns and colors in ways no hand of man or stain ever could. Meanwhile, various forms of bacteria and lichens provide texture, depth, and additional color, transforming them into highly individualized masterworks of art.
I'd buy a coffee table book with these in a heartbeat.
You should sell these to puzzle makers so they can be turned into puzzles! Seriously, my stepdad and I used to give each other puzzles like this because there are so challenging.
