Random Typography Project: jeder einzelne Charakter wird in eine zufällig ausgesuchte Schrift konvertiert. Da Schrift-Daten nicht nur Buchstaben, sondern auch Grafiken enthalten können, ergibt sich eine typographische Collage mit den entsprechenden Schriften, deren Parameter (size, kerning, leading) alle geändert werden können. Alle Fonts von dafont.com
