This very simple modules is for sites that have different seasons (summer and winter). In summer there might be a bright yellow theme, in winter a cold blue one. There might though also be different nodes in winter and summer. So what this module does is: Defining a winter and a summer theme and defining winter and summer nodes. So when the admin switches to the summer theme, the light summer css will be loaded and the user is being forwarded to the summer nodes.
