I came across a site that I will have to visit au quotidien. It is called Beautiful Portals and it's a collection of just that. Beautiful portals. The 'curators' scour the net in search of special places. They describe it as follows:
You're here, and when you go through them, you're there. They're beautiful, meaningful or just fun. They're doors, roads, bridges, corridors, wardrobes, or event horizons.
Aren't these just fabulous? Enjoy.
