Jake, is there some wider context for this article that I am missing? I ask, because at face value, it doesn't seem to me the article was limited in scope only to the advanced professionals. Of course, this wouldn't be the first time that "I just don't get it."
I sit back and think of folks like Escoulen and all the other folks doing multi-center and other kinds of spindle turning that are anything but a vessel; Springett helping to revive the techniques behind Chinese balls, as well as others making some really extraordinary intertwined pieces in this same line of exploration; Malcolm Tibbetts and his extrordinary segmented chess set, table, and chairs; I certainly consider the aforementioned advanced professionals in terms of their skill level & noteriety, though it could be that some may not find turning to be their sole source of income.
I've failed to think of peoples names at the moment, but certainly there are advanced professionals creating items that we all enjoy - lamps & lamp shades, thermometers, furniture legs/rails/styles/posts, Christmas ornaments, tops, peppermills, pens, clocks, jewlery. Most of which would be hard to categorize as a bowl or vessel.
Oh well, that's all I have.
Oh wait, I do have one more thing Jake - go Sabres!
