Tour the Heavens
This is officially cool. Check out the Photopic Sky Survey: it is a 360° x 360° photograph of the entire night sky, minus planets and moons. You can view it with information (click on the link), or optionally turn it all off to test your knowledge. Zoom in, zoom out, and check your orientation with a compass in the lower left that shows your field of view.
A lot of work went into this by one individual. Read his story by clicking on the logo in the lower right corner. Enjoy.
Божію Поспѣшествующею Милостію Мы, Дима Грозный Императоръ и Самодержецъ Всероссiйскiй, цѣсарь Московскiй. The Czar was born in the steppes of Russia in 1267, and was cheated out of total control of all Russia upon the death of Boris Mikhailovich, who replaced Alexander Yaroslav Nevsky in 1263. However, in 1283, our Czar was passed over due to a clerical error and the rule of all Russia went to his second cousin Daniil (Даниил Александрович), whom Czar still resents. As a half-hearted apology, the Czar was awarded control over Muscovy, inconveniently located 5,000 miles away just outside Chicago. He now spends his time seething about this and writing about other stuff that bothers him.
