I just found this forum, and VERY glad I did. It's given me such great ideas! And now I have a question. Does anyone know how to make a fluorescent light bulb flicker. Like in a horror movie, when the overhead lights in the office are flickering. I thought I could just twist the bulb a bit so its connection at either end was loose, but it seems that it's either on or off. I don't get the constant flicker. Any thoughts?
