We were commissioned to design the Annual Public Book Awards ceremony and we came up with a fictional journey which included the performance piece Orthographies, a set of dance phrases, underlined by live jazz music, where the performer was immersed in a fictional, interactive “Land of the Book”. Our challenge was to do everything using characters normally found in books, such as letters, numbers, punctuation marks and simple shapes (the client was in Greece, so Greek alphabet of course 
)
Here is a four minute Vimeo excerpt from the show:

We used infrared cameras and our in-house tracking engine based on openCV to track all the action on stage and we developed (or extended) algorithms for autonomous agents, particle systems, fractals and we used the box2d physics engine and much more, in order to simulate natural forces and biological behaviours in a fictional world.
We’d like to thank the good people of the openFrameworks community who were kind enough to answer our many questions over the past months, especially @arturo, @jvcleave, @zach. Also thanks to @shiffman for writing that inspirational book “the nature of code”.
