I really like this 3-D effect I get when I think about the light source for a doodle. I've been drawing many orbs lately, shadow and all. Now, when I doodle, I've been trying to add that shadow effect from a single light source all over. Voila. Here is my first full-page doodle using my new trick. Anyone can do it! Draw a few lines, then shade one side of all of them. Do it on some squiggles and it raises them off the page. The possibilities are endless. Too bad this kind of self-stimulation doesn't pay money. It's mostly just a spaced out meditation on the weird world of warping wiggles and bulging bubbles. I think I'm going to try working a figure or some people into my next one ... or at least more of a recognizable exploding head.
