I've got a t-shirt with the AR card design on it.
It's great for geeky lolz like "OMG A DRAGON IS BURSTING OUT MY CHEST!"

I think people on Facebook try to organise big meet-ups to have mass-streetpasses
It kinda reminds me of those organised sex orgies exclusively for AIDS sufferers.

Better that than pressing yourself up against school playground railings
hoping one of the kids comes close enough to give you a StreetPass hit.
