Pick one person from your team to do the presentation, or plan ahead carefully how you will divide the short presentation between speakers. Slides do not have to be transparent, since we will have the CVN room again. You will not feel time pressure if you plan on only saying a small number of things. However, you will only have a few minutes to do this, so you need to focus on the important aspects of what you've done. If you have a demo, prep it while the person before you is going, and make sure it is like 45 seconds, or probably don't bother.
Demos can be fun, especially if animation or dynamicism is going to help convey the concept.
But, in general, demos tend to be more a way to show implementation details that are not directly related to the conceptual, significant content of what you have done. Therefore, in general, I discourage demos. It is up to you. If presenting makes you feel nervous, that is normal, and you are welcome to speak with us about it. Emphasize the main points, and despite the fact that it is brief, show main numerical results, if available.
