I went to a cool drawing group this weekend where the theme of the day was "Steampunk". If you're not familiar with the genre it incorporates sci-fi, fantasy and elements from the Victorian Era and the Industrial Revolution. Here's a link that's more in depth: http://en.wikipedia.org/wiki/Steampunk. I ended up drawing a scientist/adventurer, a kind of Steampunk version of Tony Stark from Iron Man. Done with pens and Photoshop.
