This was an evening project so it isn't perfect, but is should be a nice display piece. (I would love to see how anyone's prints turn out as I won't get around to printing this for quite a while.)
Anyone who wants to sell printed versions of this has my full blessing (Attribution appreciated). {No watermarks though so do what you will.}, just don't try selling the file.
