"I suspect that religion is a necessary evil in the childhood of our particular species. And that's one of the interesting things about contact with other intelligences: we could see what role, if any, religion plays in their development."
- Arthur C. Clarke

Photomnemonic Tablet  
  A device that both records and displays images with the same element.  

I broke the seal on the dust jacket... The tablet was a featureless disk, like the blank used for grinding a telescope mirror, but darker - as if cast in obsidian. When I activated its remembrance function, its bottom-most layer turned the same color as the sun, for that was the origin of all the light now striking the tablet's surface. Because the tablet was out in the open with no lenses or mirrors to organize the light coming into it, it could not form an image of anything it saw...
From Anathem, by Neal Stephenson.

The photomnemonic tablet also had controls that would let the user page through the images in a variety of ways.

This device reminds me in some ways of a slow glass scenedow from Bob Shaw's 1968 story.
