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.
