You should definitely check out Virtuoso, an awesome steampunk webcomic set in Africa. The story is created and written by Jon Munger, and drawn by artist Krista Brennan.
Virtuoso was first released in March, 2010, and to date there are over 20 issues. This is a very original idea and a great story!
Virtuoso is an alternate history of an Africa that never existed, one run by steel and springs, commanded by vast matriarchies and past the height of its culture.
Virtuoso is the story of Jnembi Osse, a professional weapons manufacturer for the most powerful empire in the world, and how her private rebellion becomes a full scale international incident.
