Oil on canvas paper, with some colour, blending and text in Photoshop.  You can see a "Making Of..." post at my blog, The Flying Trilobite. 

 This image was done to celebrate 2008's Darwin Day, and was featured on the online literary 'zine The Eloquent Atheist, and recently I have offered prints and shirts based on this image through my reproduction shop in support of The HMS Beagle Project.  The Beagle Project plans to launch a re-created ship in 2009 in celebration of the 200th anniversary of this great scientist's birth. 

This piece was a lot of fun to do.  I'd love feedback on it.
