Stellarium is a free open source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. It is being used in planetarium projectors. Just set your coordinates and go.
One of the new things you'll see in version 0.10 regarding Stellarium's graphical user interface. The vertical bar links to windows, the horizontal bar shows toggle buttons, just like it used to.
