Ocassionally, I get tired of staring at trees or skies and whip up something to put in the background
while I work. This is one of those images. I like being able to measure browser widths as I work,
so I add the pixel ticks for popular screen sizes to the graphic. This one lasted longer than others
that I've done. Maybe because it was so soothing to me. It is, after all,
Lithium.
