Practical Application of Visual Illusions: errare humanum est

Some practical applications of visual illusions are explored for both real and virtual environments - with an emphasis on the cryptographic domain in which illusions may be employed to distinguish between humans and non-human agents. Non-human agents are unlikely to suffer the same visual illusions as we do. A Turing test differs from our approach since it relies on human-like ability rather than the characteristic human failing intrinsic in visual illusions:- "To err is human...". The CAPTCHA system for on-line challenge-based authentication can be extended so as to exploit visual illusions. In particular we consider PIX the picture-based system, and illustrate a simple steganographic application. The utility of both are discussed.
