Now I wonder if Ancient Egyptian hieroglyphics carved in stone produce any affect when the words are pronounced correctly.

I get a strong sense for sound being heavily used in ancient Egypt, though I'm not sure how this would work.

There is one image of what looks like a large lightbulb that is being used for something: [link to i.imgur.com (secure)]

Perhaps filled with the same gas that might surround the Earth, and being used with sound?

Could it be that inside of a pyramid of other structure it might work like a kind of computer when certain sounds are intoned? Is this what was part of their 'secrets of the temples'?

Hmm...
