Please recommend a software to create screensaver

[LuckyM]

hello people,
please recommend me some software i could use to create a screensaver. i want to create one (or several) for christmas for my parents, friends, etc. the free ones i find online are only capable of making a slideshow of pictures and i want to make something more interesting. so, basically, i need a recommendation for software which would allow me to create animated screensaver. i would prefer free one i got some programing skills and i'm familiar (just a little) with tools for animation like macromedia director so i think i could figure out how to make a screensaver if i had a tool.
thank you in advance for your help
