I made the old Ghost Crab Workshop logo almost ten years ago using a font I couldn't remember the name of, so I thought I was screwed. I put it aside for a few weeks.
It turns out I saved both the font and the original PSD in Dropbox! (When I didn't see them in GitHub, where I now usually keep these things these days, I assumed it was all gone.)
Also, The League of Movable Type
, the open source font foundry that made the font is still alive and kicking! And they now publish woff versions of their fonts, which is handy.
