Our take: Ghost Font is a curiosity worth a few minutes for anyone who wants to send a short message as moving dots that people can read but frontier AI models struggled to decode in the vendor's tests.
Main limitation: It is a prototype that produces a video rather than a font file, limits messages to 36 characters, and is not secure: a local agent with code execution could still analyze the motion.
