Charting the minutes of night in Helsinki - Core77
"Helsinki is one of those places that experiences extremes of light and dark, with nearly endless nights in the wintertime and almost none in the summer. Anotonio Scarponi of Conceptual Devices in Zurich, Switzerland has devised a calendar that maps out this extreme seasonal change throughout the year on a bar graph.

The months march across the horizontal axis while the hours, listed vertically from noon to midnight, index the minutes of night experienced by each particular calendar day, which is then infilled in black. It results in a solid curve of changing light, jogged twice for the time change."
