Text pattern tutorial

Hey happy Processing coders, here is a sample code tutorial coming from my latest round of Processing classes at Craslab Mains d'Œuvres in St-Ouen, near Paris. For the second class, as I was teaching for loops and functions, this generative pattern design sketch came out as the tutorial. Enjoy, upgrade and share!

(Use typical keyboard characters to write stuff, keyboard arrows to change the font size and change the font itself. Use the mouse to adjust the density, save to a file and clear the sketch).
