Like a backroom speak easy in the 20s, play a secret card game with your friends anywhere. School, federal buildings, anywhere gambling is prohibited! Just kidding. Dont do that. But, really, no need for a deck of cards, you have your phone all the time. In fact, I bet you have it on you. Right. Now. You can play on any solid surface... We havent tried it on water yet, maybe we should. Then again, water isnt a solid is it? Could this play on water? What about Plasma? Or even Bose-Einstein condensates? It definitely cannot play on a gas though. Either way, this is such ground breaking Augmented Reality tech it beats out a $3,500 headset, right? No? Maybe? Anyway, play it today, if you have your invite, that is. This is a secret card game after all.
