Again, I am not assosiated with this site in any way what so ever, I just really like their work.
I dont know how many of you use screen savers anymore, as they really are needed less and less, but if you do, you might like these: 3D Screensavers - Isotope 244
As you can see, thats not a referal link or anything. I share what I enjoy.
Also, all are malware free, but watch out for any offers while installing. You might end up with somthing you did not ask for.
