Learn how to create games with event driven programming

Scratch has been developed by the Lifelong Learning Group at the MIT Media Lab. It is a platform that promotes mathematical and computational skills as well as creativity, reasoning and collaborative working.
Scratch can be used to make a number of multimedia applications such as games, animations, simulations, stories and art and even program robots like play i.
Every object (sprite) that is used in a scratch project can have one or more scripts attached to it. These scripts add behaviours to sprites and allow them to act in anyway the user feels suitable in context to the project.
The scripts are made up of building blocks that are grouped by category, such as control, motion and sensing. There is very little keyboard input required by the user as all the script blocks are dragged to the scripting area with the mouse and 'clicked' together like lego.
