there is a whole bunch of GnuGo GUIīs avalable, the most are listet here. but one of the most interesting is not, itīs GlGo, as the name asumes it is OpenGl powerded.
but there is no perl gui yet, so keep going if this is what you whant. when iīm at home where i donīt have to sit in front of a lame Win32 workstation i will test you code and give some further comments.
btw. i whould like to have a non java gui for the kgs. if someone has tomething else than CGoban2 or is developing something, let me know.
