Yesterday they were mocking it. Today, the Sun and Mail triumphantly report that the juddering fluorescent London 2012 Olympics logo is not only bizarrely inadequate to the task of promoting the capital - it can trigger epileptic fits. "Within hours of it being launched we received 12 reports of people suffering seizures," a spokeswoman for Epilepsy Action tells the Sun.

The accompanying Talking Heads-meets-cover of-Smash Hits video has been hastily re-edited. Yesterday the multicoloured shapes were seen fizzling through swimmers' diving bodies, down motorways and up Tate Modern. Now we have footage of a cyclist being overtaken by a woman in an electronic wheelchair and elderly Britons practising their karate chops.
