The flashing logo dropped at least 17 people in epileptic seizures and officials say: Oops, we thought that might happen. Per the UK's Daily Mail:
Experts said the garish launch film had led to a number of seizures with others reporting feeling "uncomfortable" after experiencing vomiting or headaches. Meanwhile, a spontaneous public revolt over the controversial logo broke has seen nearly 35,000 people signed a petition demanding that the £400,000 image be axed.
For the currency-challenged, that's at least $800,000 down the drain. I guess this means the strobe lights for opening ceremonies are out.
