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.
