What would a Taylor Swift concert be without wristbands? Right, a lot bleaker. But it's not just the ribbons made by the fans themselves as a symbol of friendship and community that light up every performance by the artist - it's also the LED wristbands that you get as an attendee. We took a closer look at the technology behind them.

They could have been glittering red-white-red in Vienna: the LED wristbands that all concert-goers would have received during Taylor Swift's "Eras" tour. But that wasn't meant to be. Fans in other cities were luckier, as they were not only able to attend their idol's magnificent show, but also become a part of it themselves with the wristbands.
