Sometimes silly commercials are actually fun. While these may not be sci-fi, they are silly, and that counts for a lot with me. Plus, commercials invoke a discipline most audio/video creators never have to work within: tell your entire story and get your message across in 15 seconds to 3 minutes. If that sounds easy, give it a shot, and see just how it works out for you. I was surprised at the results I got the first few times, but as I worked at condensing the plot and action, I got better at it, and the stories themselves had a lot more punch in a lot less screen time.
