I've mentioned Just Wallpaper before... Now Google's getting in on the action.
Do you use the iGoogle page? If not, you should, especially if you haven't jumped on the larger RSS Reader bandwagon. Seriously, check it out.
iGoogle is now offering themes related to different causes & organizations. Deck out your page with the (ONE) Campaig or the Red Cross, or the World Wildlife Fund.
These wallpapers & themes may seem silly- I mean, what difference are they making? They're not raising any money for anything, because they're free. They're not teaching people anything in a broad sense. No one's life is being saved. Here's where I think they're valuable: Many of us spend ALL DAY in front of a computer screen. What we see affects our thoughts. By putting Invisible Children or World Hunger in front of me all day, I become aware of the issue, curious about it, and care more. A coworker or guest may ask me about it. I can talk (and blog!) about it. In the case of the iGoogle theme, it offers a link to donate to the theme's cause.
Give it a try. Maybe, together, we can create a Just Christmas.
