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. Encouraging stuff, but unlikely to thrill the "MySpace generation" who Wolff Olins originally intended to target.

The Sun asks a 12-year-old boy, a monkey, a Sun artist and a blind woman to come up with their own efforts - all "more inspiring" than the original (you may beg to differ).

Yesterday, the Mail was scathing.

"It is hard to see that the shapes are meant to signify 2012, they said, and the whole thing was a waste of the £400,000 it cost to create. Critics of the new logo described it as a 'broken swastika', a 'scribbled joke', a 'toileting monkey' and even the logo for the Nazi SS."

Fans of Googlewhacking will be interested to learn that this is the first time the phrase "toileting monkey" has appeared on the internet.

Lord Coe, the chairman of the Olympic organising committee, pointed out that the cost had been borne entirely by the private sector. But this did little to placate the critics of the cut-up fluorescent post-it note. "It is a puerile mess, an artistic flop and a commercial scandal," the design consultant Stephen Bayley tells the Times.

Thirty-five thousand people have already signed an online petition to scrap the logo - the site is rather slow, if you're thinking of joining them - and William Hill is offering odds of 10/1 that it will be abandoned by the end of the year.
