I'll keep this one short, since technically it isn't my baby any more.
Facebrick is back, much kudos to Ahmad Mushtaq for his work in locating (and fixing) the problem caused by some Facebook change or other, and also to Kamilla Bremeraunet, former GSOC student, for her work in packaging and distributing the fixed library - as well as offering to take up Facebrick maintenence, an offer I have (gratefully) accepted. :)
So, Facebrick is back in operation. Enjoy! It's great that the source is open so that someone interested can continue on with this - this is what OSS is all about.
