Long winter months where you normally have about 4 hours of overcast daylight can really have an effect on you. The gloominess spreads and makes you feel restless at times. The best way to take care of that? Well, the indoor and outdoor-lighted tent called Lyhty designed by Erkko Aarti is somewhat of a steel structured, fabric-covered igloo. This is perfect to take care of the winter despair because it is built in such a way that the geometric structure of the igloo is also cozy inside and is made to glow from the inside and outside with the light built into the frame.
