I have created a list of Fedora remixes wiki page (http://fedoraproject.org/wiki/List_of_Fedora_remixes), and I updated the Remix wiki page (fp.o/w/Remix) with a link to this list.

The remixes are separated into three primary sections, "Current", "Dormant" and "Discontinued". Within those sections, the remixes are organized by the Fedora release (ex. Fedora 20) on which their most recent releases are based, and then by alphabetical order within those release groups.

I quoted the descriptions directly from the remix projects' online documentation (project website, GitHub or SourceForge), with an emphasis on brevity. I quoted as is, with no grammatical corrections. Where the descriptions weren't in English, I did my best to provide a translation after the quotes.

Not including RHEL and its derivatives, there were ≈ 60 Fedora-attributed distributions I didn't include on the list for various reasons (e.g. if the distribution projects changed their bases from Fedora to something else, if the distributions' efforts were rolled into the Fedora Project's secondary architectures efforts, etc.). I still have a few more distributions to process.
