Hi Paul and Ian,Yes this is a well know problem. There are efforts to include SDL_gfx in Pygame. It is already a part of pgreloaded. This thick circle with unfilled pixels question is now included in the Pygame FAQ (http://www.pygame.org/wiki/FrequentlyAskedQuestions).

I'm pretty sure this problem has come up before. My solution is to draw a circle on a surface, then use pygame.draw.polygon() to clean off the parts you don't need. You can use colorkey-transparency as well to get "cut-out" arcs. Ian
