This is a logo?

The organisers of London 2012 may have foreseen some of the criticism they have received since unveiling the Olympic logo – variously derided as an uninspiring emblem, a puerile mess, an artistic flop.

But yesterday evening, they were forced to pull the promotional video for the new brand from the official website after complaints from a completely unexpected quarter – Britain’s epileptics.

In the two and a half minute animation, the logo comes alive, springing from athletes’ bodies and bouncing vividly across the city, and one flashing section has triggered seizures.

It has emerged that eight people had suffered seizures and several people had contacted the charity Epilepsy Action to say they had been affected. One section of the film, in which a diver plunges into a pool with a multicolour ripple effect, is thought to have triggered the seizures.

The causes of photosensitive epilepsy have been known for decades. There are regulations just to prevent this. Sadly, no one at the agency producing the video appears to have known that.
