I was playing around with GIMP today and I found a stock photo of a light bulb at www.sxc.hu/browse.phtml?f=view&id=190520. I tried doing things that are beyond my comprehension in a tutorial and ended up with this—it doesn't look anything like it's supposed to. This is the color version.
Update 1: This image is scheduled to make an appearance on LivingNow magazine's website (Australia) after April 16, 2009. The story should appear here.
