Artist David McCallum has a cool project that was featured on the CBC radio show Spark. The Warbike Project is a bicycle with a device that creates a sonnification of wireless network activity it encounters as you bike around. Bells play as the device encounters a new wifi network and so on. You can sign out the bike now at Interaccess in Toronto.
The Warbike turns this wireless network activity into sound. As you cycle the streets, you’ll hear the activity of this invisible communications layer that permeates our public spaces. Who knew that so much was going on?
