(1) the above show was opening night with the media.. 3000 sets of ears that they gave away.. You normally will buy an own a set of your own ears.. ($24?) which you take away
(4) The ears have both RX and TX capability... - Above you saw them running together, being controlled from elsewhere.. When you leave the show, they will interact with each other.. When you come close to another set of ears they will flash to each other..
I wished i'd come up with this idea!
