CSS is your friend.
I found that Mozilla, Mozilla Firefox, and undoubtedly other browsers weren’t making the background gradient (the cool white-to-gray pattern) look correct from the style I was trying. For whatever reason, they made the square around the pen image more obvious; I tried playing with the background-* settings, and changing gradient.gif to gradient.jpg (expecting issues around GIF patents), but no change. So now we’re trying Jaws pattern from the same style contest. Early morning silliness.
Nope, konqueror hadn’t shaken off its headache when I looked this morning, so I get to try to recreate the story from (my) memory later.
