# Customizing the training backgrounds

To customize the animated background displayed during fullscreen training:

- Choose ProVoc > Preferences > General
- Check the option Animated background
- Select the desired background from the menu

ProVoc backgrounds are essentially Quartz compositions (.qtz files). Quartz compositions can be easily found on the internet, such as from www.quartzcompositions.com. To choose a new background:

- Choose ProVoc > Preferences > General
- Check the option Animated background
- Select Choose from the menu and select the desired Quartz composition file.

## About Quartz compositions

Quartz compositions can easily be edited without writing a single line of code with Quartz Composer (part of the Developer Tools available from your Tiger Install DVD). Read the documentation from Apple

## Create your own animated background

To learn more about how to create a background that react to user actions (such as making special effects for correct or wrong answers), download the ProVoc Background API.
