which theme ussed for bbpress.org ?

Hello,
well, it’s my turn to equip my sites with bbpress. Bigger and smaller problems are slowly solving. Question: what theme is used for the bbpress site at all. And is there something like a way to create a clone of bbpress.org, with my own content of course. I think this site is very good as a start and also practical for everyday life, because it shows many possibilities what bbpress can do. Therefore: is there something like a standard installation with dummy text? Would be wonderful.
Best regards, Rainer
