"Ivan Tsarevitch" from Morevna Project: I suppose you could call this "programmer art" since the artist is also one of the main developers of Synfig Studio (Konstantin Dmitriev | www.morevnaproject.org / CC-By-SA 3.0)
We need to change the words we use for serious free culture artists. I suggest "vocational": "a vocational work", "a vocational artist", "artists who show vocationalism in their work".
I thought about this as I was considering Nina Paley's story about trying to submit some of her own (very much "vocational" and also "professional") work to the Wikimedia Commons -- only to be disbelieved on the basis that her work was of too high a quality! This concept of "professional" versus "amateur" work has bothered me for a long time. Partly this may be because I often seem to be stuck in between: am I a professional writer or an amateur one? I get paid to write for Free Software Magazine, but I don't get paid very much, and I don't get paid at all to write for Question Copyright. But both tasks are very much a part of my vocation as a writer and as a free culture advocate. I expect to be judged on the same scale as any professional.
Another objection is that the stigma of "amateurishness" is sometimes assigned to free culture art. People speak snidely of "programmer art" (though of course, a few programmers are quite good artists, and vice-versa). I honestly believe that some artists hold back from freeing their work not because they are really worried about remuneration, but because they fear that releasing it for free will somehow cheapen the work (or them) by making it "unprofessional" or "amateur".
Of course, I'm bothered by that idea in itself. There's something a little dirty about the fact that we have so elevated commerce that we now implicitly place professional work (made for money) above amateur work (made for love). Surely there ought to be something a little more holy about work gifted to the world out of an artist's spiritual need than out of their need to pay the rent? (Not that paying the rent isn't important, but there ought to be some respect for the long perspective).
