Visual Programming with Processing

As an introduction, I make students draw with digital means. Processing makes it very easy to program lines and forms. Many key issues of programming are learnt and transformed into small visual applications. After that, the aim is to use the specific properties of the computer as a medium for visual purposes. What does it mean to draw images by means of an algorithmic code, instead of drawing them by hand? Examples from the history of computer art will be shown and discussed.
