KEVYK Actually all the scenes that are downloaded are demoable. There are 4 of them in all in the demo and 40 of them in all in a purchased product. You can choose which scene to evaluate right from within Serene Saver Pro's System Preferences under its Scenes tab, or if you choose you can just do nothing and Serene Saver Pro will automatically and randomly choose a scene for you to view every 1/2 hour. You can also program this interval anywhere from 5 minutes to once a day.
I hope that helps,
