If you're the kinda person who tends to be quite observant about the things that you come accross in the city chances are you're familiar with the paste-up style of street art. It's a style that has been quite popular for some time and around the streets of Berlin there's no exception. However locally based artist SWEZA is taking the form one step further with his cool new project QRadio, which croses audio, street art & mobile technology all at once - and it's actually pretty sweet.

Instead of pasting up his quirky beatboxes around the place he also makes them interactive. With each box - there are 5 in total and moroe to come - he places a QR code on the front, rewarding those curious or observant enough to check it out with a unique treat in the form of an audio track that you can pick up with your QR Code reader on your Smartphone.
