THE WOW MOMENT
Walking through Kyoto at sunset, your phone buzzes: "3 friends are tumbleweeding with you!" You see their avatars rolling along your route. One types: "That shadow on the temple wall at 6:42pm—that's where we're meeting!" Meanwhile, your origami sandal's solar inductor has been charging your phone the entire time.
