I'd arrived to see a wide collection of Nintendo Super Mario merch, clothing, and toys, but I was transfixed by the morphable image of Super Mario's face on a nearby iPad screen.
Hello Mario, which arrives in the US on February 19 in the App Store and Google Play (and will be available in Japan after a few months), is a free and oddly engaging app that doesn't do much, but somehow perfectly conveys the ethos of Mario's antic personality.
