So the situation is you're having a party at night. You are setting up the decorations and want something out of the ordinary. You start thinking. Hmmm, what about a disco ball? Wait, all the shops are closed this time at night. What do you do?
Make a virtual disco ball! Using your computer, you can create a disco ball that looks quite real, in my opinion. The idea is create different "frames" of the disco ball and put it together into a video. During the party, or whatever the occasion, just play the video in full-screen.
Step 1: Materials
You'll also need a video editor. I personally use Sony Vegas, but you can use Final Cut Pro, Pinnacle, or whatever. If you don't have one, MovieMaker should be fine. MovieMaker should be built into your computer if you have Windows XP or Vista.
You should also have experience with image and video editing.
