For some time now, we've all seen cars with little metal fish screwed into the rear end where the model and dealership's name sometimes are. Most people know that the fish is a symbol of Jesus Christ, whose name is often spelled out in Greek inside the fish. It's a way of spreading the evangelistic Christian meme complex.
Evangelism is an essential component of a virus of the mind.
The fish on the back of the car is but a small means of taking the message into the age of advertising. I laughed the first time I saw this, but then started to think. If not, it's the kind of thing that should be done. Most people's experience of science is a boring high-school class with impenetrable textbooks and difficult exams. If scientific ideas could be as fun as astrology, and be as good ice-breakers at parties, we'd be on our way.
