an interesting tidbit in the Pokemon article linked by Jonno:

"In 1991, an American woman named Dianne Neale suffered seizures from hearing Entertainment Tonight co-host Mary Hart's eerily perky voice. Her doctors said Hart's electronically transmitted voice triggered Neale's epilepsy by creating abnormal electrical charges in her brain (MSNBC 1997)."

this isn't news. she does the same thing to me and millions of other people.
