Sunshine is an important aspect of life that we don't really take into account. I read an article a while ago about a town in Norway where for a portion of the year, the mountains completely block the sun from hitting the town. So an artist got up on the the hill and built a giant mirror so that the town square would have some sunlight. Interesting parts about this map are that the band of light blue that goes across from northern France through Slovakia. Now it gets me thinking, what factors influence the level of sunlight in a given area?
