In Finland, there are two distinct phenomena associated with lighting conditions. In the summer there are white nights when the sun never sets down. It takes a while to get used to sleeping during those nights. In the winter it might happen that the sky is gray during the whole day. It feels chilly on such days. This is why there are so many electric bulbs in Tampere. I noticed it soon upon arrival that people here like various electrical equipment. For example, they have bus schedules near each bus stop which are made of the bulbs as well.
I have taken pictures of these nice figures. As you can see, a whole story is told using this innovative form of art. And it makes life so much more exciting.
