In Moscow, St. Petersburg and many places in general for quite a long time in a year, people are deprived of the opportunity to see the sun. During the day it is hidden by clouds. At night, of course, there is none; and the night takes in the winter time in general most of the day.
For me personally, this problem is not very serious, but many complain that the sun in the window can not be seen. I propose to give them at least an appearance, to feed the emotional sphere, even if illusory. Maybe it will be easier for them to wait for spring?

A pseudo-sun can be hung by the window on a string or glued directly onto the surface of a window glass. It is easy to draw it on any paper that has practically come to hand. Or you can not draw - in a democratic format .jpeg (444 KB) The pseudo-sun lies
behind a special link and is waiting to see any color printer.
Yes, the business model of the idea, of course, no :)
