I guess some of the screensavers in Ubuntu are nice. But I'd really like more. Is there a website with screensavers for Ubuntu?
Also, I am particularly looking for a screensaver that looks a bit like Mac's ribbon ribbons of light thing.
sudo apt-get install xscreensaver-gl-extra
There's a nice once called Flurry but it's quite intensive on the computer and not a very energy-efficient method of not using your computer.
Here's what it looks like:
Edit. There's a whole load more in xscreensaver-data-extra
too if you want something different.
I'd recommend Electric Sheep. Electric sheep automatically downloads various sheep and you can upvote the ones you like. More popular sheep are displayed more often and vice versa. For more information see electricsheep.org.
electricsheep
in the terminal produce? Also run electricsheep-preferences
and test your connection. You may have to wait for some sheep to be downloaded first.
You may also look at the Ubuntu Software Center for the GLX Screensavers, those are a port of the famous Really Slick Screensavers for Windows and Mac.
Those screensavers have the look and feel of great Mac/Windows screensavers.
