Acoustic archaeologists are exploring how the Chavin culture in Peru may have designed underground temples to blow worshippers' minds using low-tech sound and light shows. Of course, this thread continued in cathedrals with massive stained glass windows and organs all the way to today's high-end multimedia megachurches. According to Miriam Kolar of Stanford's Center for Computer Research and Acoustics, the temple's maze of tunnels "could be physically disorienting and the acoustic environment is very different than the natural world," and might be especially freaky for folks who were tripping balls.
