QR code and laminating fun

I prepared a lot of handouts, posters and other items in preparation for the Surya Eco Yoga Camp.  'ö-Dzin bought us a new toy—a laminator—and I had great fun making posters knowing that they would survive whatever the weather throws at us at the camp.

QR codes are a new discovery for me and I have created one that points people to this blog.  I experimented with colouring it and found that my mobile could still read it as long as the contrast remained good.  Hopefully people will walk past Tharpa Ling with their smart phones and pick up the link.

Some people have done fancy and interesting things with these codes – there are many displayed on google images.  I think it is interesting that they can contain text rather than just be a link.  What do you think of them?  Do you find them useful?  Both of these colourful ones work.
