Recently I visited Drammen, a lovely town in Norway. It is a very nice small town, with cosy city center and a super modern university college. Also Drammen has a unique bridge, which is y-shaped. The bridge is vibrating and "communicating" with two large balls, one on each side of Drammen river. Those balls are turning vibrations into some kind of music. Too bad that I didn`t manage to upload video here :( But it sounds like ambiental music! It is amazing!
I love great architectural solutions!
