Well, my older daughter usually changes the screen saver to what ever, like a picture of her with her friend, a picture of the woods she took at the park, her sister holding a big bass she caught her self and now it's a drawing she did of her own. I never know what's going to be on there until I log on.
I always set my computer to deactivate the monitor instead of using a screen saver, we all have to do our bit for the environment and powering peripherals down is a good step!
I have my Dad (who is now aged 80), hulahooping in our friends garden with their 3 legged dog named tripod. I kid you not! This reminds me of when he was fitter and makes me sad sometimes, but also makes me smile.
I would like a screensaver that has the solar system revolving around the sun
