CodeLab
Go here to sign up for or log on to CodeLab. I will assign a small batch of CodeLab exercises after almost every class. Ideally you will do those exercises right after that class and before the next class session. Once a week (on Wednesdays), I will check whether you have completed the CodeLab exercises due during the preceding week.
To get started with CodeLab, register (you should have gotten an email from me about that; let me know if not) and log on. If you go to the "help" page, you can watch a video that shows you how to use CodeLab. Then you can do the first few exercises. There is a batch of very simple exercises called "Getting started". Later batches always have the date of the class that they go with.

If you google for "gimp transparent background", you will find loads more.
Background music and image
Here is an example of the pop-balloon-game with background image and music. You as also need the following image and music files:
