I love this, of course, but does it still work for the postmodern kid who recognizes and embraces the flatness of the screen?
Maybe this needs to be reworked as a two-iPhone near/far teaching app that uses GPS. Or at least Bluetooth.
Who needs iPhones/GPS/Bluetooth when we have active shutter glasses?
I think the postmodern child needs Grover to show near vs. far one just one time more for it to really sink in. OK Grover? Maybe two more times.
