Another project by Oded Ezer, Typosperma is the second experimental typo project in his 'Biotypography' series.
As a paraphrase on the biotechnology definition, 'Biotypography' is a term that refers to any typographical application that uses biological systems, living organisms, or derivatives thereof, to create or modify typographical phenomena. The main idea of the 'Typosperma' project was to create some sort of new transgenic creatures, half (human) sperm, half letter. These imaginary creatures are cloned sperms, that typographic information has been implanted into their DNA.
