While riding the subway to work in Toronto, Jonathan Hung noticed a poster promoting the Lord of the Rings musical (who knew?) at the Prince of Wales theater. What caught Hung’s attention was the poster’s encouragement to fire up the bluetooth or infra-red on his phone, point it at the poster and get a free ring Lord of the Rings-themed ring tone. While Hung says the musical isn’t supposed to be very goo but the ad is a lot better than all the “take one to learn how to speak any language” ads that seem to be everywhere.
