When you look at a TED talk, you will see the speakers stand on a red circle carpet. It is an outline of standing on the “spot”, standing in the spotlights to present something.
You could replicate something similar. It is especially nice if you need participant from your audience also present a thought / something short. Use a carpet to cut in a circle and use that for your presentation. Do make sure that it is not easy to trip over. You can also use some alternative materials to make such a round circle. For example a piece of artificial grass. This will create a special effect especially when it is well positioned in the theming of your presentation.
