Nikola Tesla created such vibrations
For entertainment, Tesla once convinced his good friend Mark Twain to test out a vibrating platform in his Manhattan lab. Twain took him up on the offer and found it to his liking. When Tesla commanded Twain to come down off the platform Twain refused because he was having a good time. A few minutes later Twain ran from the device. It seems that Tesla had deliberately neglected to tell Twain that the vibration tended to cause diarrhea.
