For me night time is MAGIC! I love the colors and what you get after a long exposure. Here are some examples (ok, some are not strictly night time but twilight...) The full screen option on the lower right corner is great, check it out!
IMPORTANT NOTICE: The "view this in 3D" button is just an advertisement of cooliris, from whom I got the photo gallery plug-in, it's nothing really. To see virtual panoramas please go to that section of the site.
