Like a phoenix from the flames, a great idea rises again.
Some time back over at SpreadFirefox.com, we started an effort to make a college poster to help spread Firefox. The results of this effort was a great poster that showed a rear view close-up of a person wearing bluejeans with a Firefox-wrapped condom in the hip pocket. The slogan was "Always use protection." Everyone involved loved it and we were days from taking it to print.
The project was spiked because of concerns that it would offend some people. One of the participants in that poster effort has revived the idea and while it's not a poster, this variation makes a very nice desktop image. Go check it out at mandolux.
Thanks to Chris for the heads up.
