Someone created a 'Ghost Font' that humans can read but AI can't - I had to try it for myself

Key Points:
- Ghost Font is an experimental typography project by Eric Lu that hides letters within moving dots, relying on human motion perception rather than visible shapes to reveal text.
- The illusion confuses many current AI vision models because they analyze video as sequences of static images and lack the natural ability to integrate motion over time like humans.
- While AI can struggle to decode Ghost Font initially, advanced techniques such as optical-flow analysis and frame-by-frame examination can help recover the hidden messages.
- Ghost Font highlights fundamental differences between human and machine vision, similar to how CAPTCHAs exploit perception gaps, but it is not intended as a security or encryption tool.
- The project offers insight into the evolving capabilities and limitations of multimodal AI, showing that some aspects of human visual processing remain challenging for current models.
