Der Einstieg in das IAD-Studium erfolgte mit Basics zur Programmiersprache Processing. Angeschaut wurden zu Beginn die grundsätzliche Syntax mit Semikolon, Klammern, Funktionen und Parametern. Auswirkungen beim Verändern des Codes wurden bei der ersten Aufgabe einfach ersichtlich. Es galt Smileys in neun Stimmungslagen zu zeichnen. Resultat siehe unten. Was auffällt im Vergleich zum Informatikunterricht an der Uni: Anstelle von Variabeln erstellen, Werte zuschreiben und diese dann zusammenrechnen, programmiert man hier an der ZHdK von Beginn weg mit dem Ziel eines visuellen Outputs. Sehr cool.
