It's time to write some text on the screen using the text() function. The first parameter is the text you want to display, and the second and third parameters are the x and y position. With textSize() you can control how large the text is. If you call fill() before calling text() you can set the text color.
After some basic text() calls we create a program that writes anything you type on the screen. Each letter is written on a random position and with a random size. The letters then quickly fade out and disappear.
