I don't know why this story that Forbes ran in April and I linked to in August hits Associated Press just now, but the picture is too good to miss, so here it is again.
"Nippon Telegraph & Telephone Corp., Japans top telephone company, says it is developing the technology to perhaps make video games more realistic. But more sinister applications also come to mind. The technology is called galvanic vestibular stimulation — essentially, electricity messes with the delicate nerves inside the ear that help maintain balance. I felt a mysterious, irresistible urge to start walking to the right whenever the researcher turned the switch to the right. I was convinced — mistakenly — that this was the only way to maintain my balance."
