I came across fold.it and downloaded a copy of it. But if you are double-clicking the executable and "nothing happens" it might be that your Fedora is missing a library.
In my console I was having this error:
$ ./Foldit
Foldit Error: The game has previously not started up correctly.
If this problem persists, please install the latest version.
Foldit Error: Could not load library: libglut.so.3: cannot open shared object file: No such file or directory.
So, in order to make it run, you need to install the freeglut library:
$ sudo yum install freeglu
That's it.
