Undefined
At a workshop with Billy Kiosoglou of Brighten the corners we experimented with the sentence “I think, therefore I am.” based on personal features from our childhood.
Because of poor memory my childhood I gave it the attribute undefined. Another aspect was the number seven, which appears again and again in my past.
I manipulated the svg-vector-data of the sentence set in Helvetica by replacing every seven in the source code with a zero.
