There's this artist in Pennsylvania named Dave Barkby who'd got a really big lathe
He uses that lathe to turn wood burls into decorative wall art.
This is a wood burl.
cut out a slice of it, put it on the big ass lathe, and carve something beautiful out of it.
He's got a bunch of really beautiful turnings on his website. Check it out. http://www.barkbywoodsgallery.com/page1.aspx
