Free Entertainment at Denver Airport (DIA)

Crusing through Denver International Airport, I spotted several interactive billboards by 1st Bank.

Scan the QR code and you can download sodoku, crosswords or a book! You need a smartphone, and most Blackberries and iPhones work. Each time I passed a billboard, someone was trying it. Lots of well-deserved press buzz too for the Boulder, CO agency that created it.
