Well, I saw this on Kenny's journal, and had to bring it to the attention of the people who read this journal.

A site called AntiWar.com offers a casualty counter. I can't put it up here because it requires that you put a few javascript files in the same folder as the page you have the counter on, but I think it's not a bad idea. It's become far too easy to forget that there is still a war going on. This is a not-so-subtle reminder.
