This is an example of Processing to learn: -To use Text to Speech library (ttslib) -To draw shapes capable to follow mouse position -To introduce an image using PImage and insert into desired screen coordinates -To control the frame rate -To assign randomly or according to Perlin noise diferent face colours. -To execute something when a key is pressed. -To change mouth and eye shape using a conditional statement  face
