This lesson is called The Big Event.

It's all about how we can control our programs,and actually change the way a program runs

on the fly, using Events, like the push of a button, 
or the click of a mouse.

For this lesson, you'll be 
using a paper controller.

It's just like a real life video game.

An event is an action, 
that causes something to happen.

It's like when you click the button on a 
mouse and a webpage loads, that's an event.

When you touch your screen on a tablet to
scroll, that's an event also.

Events are a great way of letting the user
direct your program,

whenever they need or want to.
