Munzee, munzee, so good to me

If you want to wow your grandchildren with your knowledge and expertise in using your smartphone, this may be the app for you!
It uses QR codes, those strange square maze-like images that you’re increasingly finding on packaging, books and even television advertising to provide the basis of a treasure-hunt game. Click on the Munzee logo above to get started.
The idea is that you search for “munzees” in your local area, shown on this map thus  
 
 

There’s a Munzee somewhere here – Devonport, Auckland, NZ

… and when you find them, you record that find on your smartphone by scanning the QR code that is on a lamp post, or even under a bench.
If you then want to get really adventurous you can start “hiding” your own munzees and adding to the fun of others.

Anyway, just a bit of fun that I thought I’d share with you to illustrate how QR Codes can be used.
Scan this one and it’ll take you straight to Wikipedia.
