i have 4 GB of RAM on my Macbook, but my browser is open most of the time and there is zero desktop even showing so it's not worth it to me. i might check this out for my Mac Pro on my second display where i have email and iTunes and much desktop showing. i'll have to film some Kansas wheat fields blowing in the wind next time i am visiting my mom as i think that would be a nice little window to home.
I gave this screensaver a try... not bad at all. I'm quite pleased with how far they've come over the last few years with regards to memory management. I still don't care for a moving desktop, but at least this screensaver doesn't bleed your CPU dry while running.
