The Generic Mapping Tools ( http://gmt.soest.hawaii.edu/ ) should be able to do what you want if you're wiling to put in a little time. Fractal Terrains from ProFantasy has a similar-looking interrupted projection image on its page ( http://www.profantasy.com/products/ft.asp ).

When you say "Blank Map", what do you mean? Just coastlines, terrain, something else?

Is your interest in an interrupted projection or specifically in the polyconic projection?
