Imagination

If you like to think about the cosmos (like I do) - its galaxies and planets and beyond - this is a nice clickable way to navigate the almost philosophical musings of the great physicist and dreamer, Carl Sagan. Instead of watching one of his programs all the way through, however, here - at the end of each clip - you can choose your next "adventure" through the skies. Not a very complex new idea, but enjoyable and relaxing. -- Tracy Swedlow, [itvt]
