You can see how the stars of Ursa Major looked 100 thousand years ago, how they look now and how they will look in 100 thousand years. You can see how the stars smoothly move relative to each other during this period of time.
More detailed video with subtitles and stops at 50,000 years ago, at present and at 50,000 years later you can see here: Ursa Major Changes During 200 Thousand Years.
The video was made using own software. Information about the stars is taken from the Hipparcos catalogue.
