I'm a big fan of the $1 Unistroke Recognizer - it's just so cool that it works so well with minimal training. I was itching for a reason to use it and threw it into a flag semaphore decoder. Then I realized it was completely the wrong tool for drawings with only (8 choose 2) combinations where rotation does matter, and did something else instead. So, I'm still itching for a good reason to use it.
