If the look of Speegle reminds you of Google...
Google has no connection with Speegle and the use of bright colours is simply to make the site more visible for those with visual impairments, said [Speegle's Founder] Mr [Gordon] Renton.
"It is not a rip-off. We are doing something that Google does not do and is not planning to do and there is truth in the saying that imitation is the sincerest form of flattery," he said.
Postscript: Google does something like this, or at least did, at Google Voice Search. It was created ages ago but no longer appears to be working.
