The most important thing to us is probably the demo. And by demo we mean a working prototype of whatever you plan to build. Mockups can be helpful too, but they're much more convincing if they do something. Even if you have nothing now, you should be able to build something in the time you have.
(Demo = live. Please don't make a video. We won't watch videos.)

If you haven't actually launched it yet, maybe a video is ok? Or you may want to make something in a wireframe program.
