Is there a simple way to convert an .scr file into something that would work in OSX? There is a famous German screen saver that I've heard about and I can even download, although I can't for the life of me get it to work.
"Screen savers are executable files that run when opened; they can display vector graphic or text animations, play slide shows, animation, or videos, and may include sound effects."
A windows executable file is not going to run under OSx. You would need the code source and then you'd have to figure out how to make that work on OSx.
