Using previous accounts I had posted a possible solution for Moon Phase Symbols with pstricks (How to typeset moon phase symbols?) and a suggestion to print numbered Go stones (Typesetting Go Diagrams with sgf2dg)
My very first question on stackexchange was this one about strange spikes that appear with PSTricks and XeLaTeX.
I have asked a question about typesetting Go stones here: Sgf2dg and Perl: Use of uninitialized value $_ in pattern match (m//)
