Check this awesome video, about night ice climbing.

The Frost Giants of Norse mythology were huge, cold and practically indomitable. At night they taught the people of the North to fear, only to freeze again the next day. In January 2013, extreme sports photographer Thomas Senf headed off for Norway with a team of fearless Mammut ice climbers. The plan was to set the professional athletes against the nocturnal backdrop of the legendary world of the Frost Giants using flares and spotlights. The project produced unique photos, the likes of which the world has never seen before.
