I'm the kind of person whos always waiting for someone to rescue me. I look around at our world and I see a lot of people who need rescuing. The idea that I could help find someone who could do that rescuing by my choice of screensaver is amazing.
Basically I've watched too much Star Trek, Babylon 5 and Dr Who and read waaay too many Anne McCaffery novels.
