I can't remember where I read this anecdote, though I may if I begin writing it out - It was observed by a foreigner that some monks in the Himalayas who were building a monastery on a high up cliff, could levitate and direct large blocks up to the cliff from below using a specific orally delivered tone directed by long mouth horns of some. Maybe I read it it on a website that was talking about that Russian guy who used insect outer shells to build a levitating platform. I forget his name too. I'll update this if I remember either.
