Curious sightseeing

I just rediscovered the September copy of Wired which I bought on the way back from Cali.

There's this article about a new way to use your SMS equipped mobile phone to do sightseeing. You just stick a yellow arrow sticker with a unique identifier next to any point of interest and a passer by sends that unique identifier via SMS to the number quoted and gets the text that's been left about said point of interest. Very cool! And even better: it seems to work worldwide.

Don't be surprised if you see yellow arrows popping up all around you all of a sudden...
