For a production of To Gillian on her 37th Birthday I need a sliver of light to shoot across the stage on the actors faces (to represent a shooting star, however more symbolic than realistic.) We have decided to go with a cheap DLP projector mounted on our position similar to a balcony rail(we don't have a balcony.) This is going to be the only effect the projector will be used for and will be repeated several times. When it is not used it is to be black. We are not going to worry about the "video black" as the director likes this anyway for scene changes. I have very little experience with flash however I think that this would be the best program to create such an effect. My general idea is just to create a simple motion tween of a white blob on a slight arched path (we are going to fuzz the focus of the projector.) However I would like to be able to control this with the enter key or possibly a mouse click. I would like to have a black screen, and when the enter key is pressed the animation executes, leading directly into another black screen, which I could then trigger the animation again and again by the enter key or mouse click. I have no idea how to do this or a method to get this animation to go full screen so no windows stuff will be visible. Is there anyone out there that can help me or provide suggestions?
