I found this interesting video whilst looking through archive.org.

The description on the site says the following:

Through religion, philosophy, psychology, art, and architecture, RADIANCE presents light as a universal symbol of life. This film invites the viewer to see how images of light continue from ancient cultures through modern times, connecting the visions of people throughout the world. Natural images, unusual special effects, and poetic narration are woven together with musical selections to develop an evocative documentary on light, from the metaphysical to the physical

Regardless of your opinions on what she is saying, there is some truly fantastic imagery going on. Well worth a look.
