Yard art. I've seen similar, but not my cuppa, no interest in making stuff like that at all. But my older son has made some pieces, none with spoons, and has no problem selling them for $40 a pop. He complains about not having enough money, but doesn't make this stuff often. Here's a few examples, not of his work, but stuff I saved to forward to him for inspiration. Do a search for yard art images and you'll get a whole load of them.

Some days, the supply of available curse words is insufficient to meet my demands.
.....Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
