Haptcha is part of a larger brand that has a microsite where the typeface can be downloaded and a set of double-sided posters that can be used for promotional material and specimen sheets as well as see below

With calligraphy there was such a set way of doing things that unless you could technically out do the next guy it became just a matter of production.

Captcha is actually an acronym for “Completely Automated Public Turing test to tell Computers and Humans Apart”. The type with which most internet users are familiar, in which you are required to decipher the glyphs in a distorted image and then reproduce them in order to identity yourself as human, was invented by a team working at for the search engine AltaVista in 1997. Their aim was to prevent bots from automatically adding addresses to their database. The story goes that they created the solution by analysing the manual for their office scanner they simply implemented the discrepancies that the instructions said would result in poor OCR (optical character recognition) in parsing text documents. 

It has to be able to work as a display typeface as well as a informative way finding design. As it will be used on the signage both large and small for directions. It will be displayed a visual brand of the exhibition. The past generations of typefaces such as Beowulf, Elektix, Dead History and ZXX have taken there inspiration from technology of the time but there hasn’t been a typeface that specifically focus on the form generated when creating a captcha.
