Essentially it's a mash-up between the bbPress support forum theme here and Kakumei, with a few tweaks.
Requires the Topic Views plugin to be installed.
It's older work and not as pretty as "FutureKind" (I won't be releasing that one this year) and you can forget about "validation" unless you want to work on it quite a bit yourself, but it's a nice alternative to the defaults.
Let me know if you get any errors or other problems.
I'll try to fix it up some more as I have time.
