Yesterday on the awesome Astronomy Picture of the Day (APOD) website, they had a very cool video from the 1960's dealing with the sheer range of scales of the universe we inhabit.
Check it out, it takes about 9 minutes to run but is practically guaranteed to change the way you look at the universe, both on the macro- and microscopic scales. It also happens to be of quite (if I may indulge) stellar quality.
It's also cool in me in my dual role of physicist/astronomer, because I know and care for things on both extremes of that scale. I thought the rendering of the atoms as an indeterminate flurry of motion was particularly awesome.
