This site includes movies and sound. If these fail to play back even after you have been waiting for a while, you should download and install the following free plugins. For movies, click here to get the QuickTime plugin. For sound, click here to get the RealOne plugin. These plugins are free of charge. If you receive messages saying "your free trial has ended" and inviting you to pay money, you can safely ignore them. What they are trying to do is entice you to buy the "full" version which you don't need.If you still have problems after installing these plugins e-mail Martin by clicking here.
