@teschy: Man, that map is awesome. I absolutely dig the nebulae with the symbols for ice, radiation etc.
Only two suggestions: if you look closely (maybe tune up the brightness in order to see it), the edges of the Barrier nebula layer are visible and give it a cut-off and artificial look ('specially left of Edinburgh and below Dublin and Omega-47).
Also, I'd prefer the system names in white, 'cause it's a more neutral colour - but that's just my taste:)
Anyways, great work! After seeing you guys 'n girls so actively designing, I'm really craving to get PS running:P
