This idea isn't branding related, but kind of is as it is game day atmosphere related, which also could look good on TV. I believe one of the best game day things added in the recent past is the addition of the tornado siren after scores. It's fun, unique, and relates well to a Cyclone. However, in addition to that, myself and my friends put our hands in the air, all while making a circular cyclone/tornado swirling motion while the siren blares. You can get your hips into it too. Maybe I'm wrong, but we think it's fun, looks cool, is unique, and everyone around us seems to get a kick out of us doing it. Sometimes we even get others to join. Now imagine if the whole stadium did that and what that would look like in person and also on TV. To my knowledge, nobody does anything even close to that.
As much as I hate hearing it when Iowa is playing in Ames, I agree. The tornado siren is pretty badass.
