A segment of animated footage promoting the 2012 Olympics has been removed from the organisers' website after fears it could trigger epileptic seizures.
Prof Graham Harding, who developed the test used to measure photo-sensitivity levels in TV material, said it should not be broadcast again.
Charity Epilepsy Action said it had received calls from people who had suffered fits after seeing it.
Organiser London 2012 said it will re-edit the film.
Certainly sad for the people who were affected, but it's another fascinating window into the marvelous organ that keeps us breathing, thinking, talking, moving, and feeling. How in the world could seeing a certain combination of motion and light cause a "short" in the brain and initiate the kind of fireworks that translate into a seizure?
When I was very young and changing the version of "what I want to be when I grow up" every few months, one of my more lasting visions was of becoming a researcher in neurology and brain injury. Don't read anything into the fact that I had nine children instead...but I've never lost my intense interest in the workings of the brain and the implications for education, for treatment of stroke and Alzheimers, and for therapies for paralysis. So even an unfortunate event like this one continues to pique my interest
The writer of the above article was careful to state that it was not the Olympic logo itself that caused the seizure, but the promotional video for the logo. But...have you SEEN the LOGO? When I first saw it, I thought I was getting one of the visual auras that precedes my migraines! They probably paid someone big bucks to design that thing...I mean, WHAT IS THIS??
