Fingerboarding demo... kinda cool(?)

I remember finger boards... don't remember anyone having a mini-skatepark to use them on. I watched the vid and thought yeah that's kinda cool but hey so were yo-yos and hula hoops (for about 5 minutes). It reminds me of the episode of the Simpsons when a group of yo-yo pros (and yo-yo salesmen) entertain the school, then every kid buys a yo-yo and proceeds to suck at it. As it should be with fads.
