People make some incredibly good and intricate drawings with the old Etch-A-Sketch. (A Google image search can give you some examples.) I don't expect anyone would be able to accomplish anything like those, but that's what gave me the idear.
I reckon there'd be nothing wrong with altering the settings in your local game to make it easier, though bonus for a screenshot showing you in an actual server with your image. And of course, no Photoshop.
