Identify a Font by Answering Questions About It

The page flow is too confusing I think it would be better as a fullscreen list narrowing search

I used this app today to figure out a font that I have been wondering about for a long time. After about 30 questions, it got it correct (at least the answer looks identical to the font I've been looking at for so long). Very useful app.

Powered by a Common Lisp program, too.

I ran through it providing answers for Gill Sans and I got back 30 possible fonts. Gil Sans was near the bottom. I guess this is pretty useful if you're working from a picture of something.
