This is a simple MultiModule file of Boris running around on the screen :)
In the System Folder, drop the file into the MultiModule Folder, located in the After Dark Files.
Bring up the After Dark Control Panel.......click on Boris and adjust the number of cats to your desire. Same with butterflies ( I have none.....I just like to watch Boris zip around the screen :)
Click on Multimodule and pull down Boris on Screen. Voila!
