RoboFab looks interesting but unfortunately seems to be abandonware. The docs imply it should work under Unix, but nearly everything I try to do tracebacks with a message about GUI elements only working on MacOS or Windows. An email to the info address on their webpage bounced back undelivered after a few days. The wiki is busted, and the Google group lists three messages total, two of which are test messages. And the licensing situation is complicated, which would discourage me from contributing improvements to RoboFab or releasing any program I wrote using it. It’s not an initially inspiring project to get involved with, but I’m going to keep hacking, as there are a myriad font-creation tasks that could be partially or completely automated with something like RoboFab.

t.26 has two nice modern blackletter faces, Wexford Oakley and Nightjar, plus one just plain crazy face, Tonic In Gear.

I’ve posted on Typophile work in progress on Ljubljana, a face I started working on in 2005 during my European trip which began in the city of the same name.
