The Nintendo booth at E3 has a curious station featuring a screen with its most iconic characters, Mario and Luigi. The booth let people go up to the characters and hold a conversation with em (which you can see above)—which is cute, but also kind of eerie for some reason.
I'm curious as to how Nintendo pulls it off, because it was obvious that the characters could "see" what was going on around them—they'd call out to people in the audience or to those passing by. Maybe it's a trick, who knows!
Funnily enough, Luigi—unlike Mario—had to kind of beg to get someone to come up to talk to him. Aww, Luigi....
