Over the weekend I was asked a question about QR Codes. What they are and do people even use them. Basically they are an advanced version of the bar code and in my opinion the idea hasn't really caught on - certainly not here in Western Australia.

I occasionally see businesses use them, but as most people don't know what they are or what to do with them, I wouldn't have thought they were of much use - yet. I'm sure it wont be long before the popularity picks up some more.

Coincidentally, TechCrunch posted a new article explaining that Facebook have painted a giant 42 foot QR Code on the roof of one of their buildings.

When the Hackathon was announced, most employees imagined beautifying the campus with posters 
and spray paint murals but Mark Pike had something bigger in mind. “It started with a comment on 
Zuck’s post. I wrote, "Hack yeah! I'd like to paint a gigantic QR code somewhere so we can RickRoll 
online maps, or point people to our careers site, or send them to a 'Clarissa Explains it All' GeoCities 
Page" Pike says.
