Holli Dance simulates nightclub lighting and can display a strobe light effect. Unfortunately, some people can be harmed by strobing light, so as a safety feature, I have included this file in the HolliDance directory. As long as this file is present, the light stobe effect is disabled. To enable the light stobe effect, simple remove or rename the file. Light strobing can be disabled again by creating any file with the name 'NoStrobe' (file size, type, and contents are not important). I apologize for this complication, but some folks can really be injured with strobing lights and it's best not to take chances!
