The Tubakuba is a Scandinavian cottage with a front door that's like crawling through a black hole.
From the foot of the snowy, picturesque massif that residents of Bergen, Norway, call the Seven Mountains, the Tubakuba looks like any number of modernly designed rural cabins. It's a small cube of wood and glass, perched semi-precipitously upon a rocky incline: the sort of retreat that any writer would give his eyeteeth to call home. But it's when you approach the Tubakuba from the back that the cabin truly takes your breath away: it's got an entry portal that looks like a hole torn in space-time.
