Following two weeks of brainstorming and creative moments, I'm proud to announce on behalf of our team of students: QRAZ.AT

The idea behind it is to place stickers and posters with only QR codes on them across the city of Graz. People with smartphones will be able to scan them and will get an URL which redirects them to various webpages, based on logic which turns them into playing stones for games like a scavenger hunt or give them coupons and advertisements.

I'll provide more information once the first batch of QR codes has been deployed in the city.
