Then I was pointed to the comic Girl Genius (published online and free to read), and was instantly hooked. I can't believe I've only now found out about this masterpiece. It took me only about four days to read the first nine volumes (doing very little else during those days, of course). Now I'll somehow have to adapt to reading it just a page at a time as it's published. Not necessarily an easy task.
Last, I started to wonder whether there's any good steampunk themed music. Through Wikipedia I found Vernian Process, a darkwave band (they describe themselves as 'steamwave') with Jules Verne/steampunk themes. I've just listened through their album Behold the Machine, and it's not half bad. What's more, you can download it for free from their website.
