WebMynd launched a new contest called “RedesignGoogle” that invites designers from around the world to give Google search a makeover by installing user-submitted designs from an online gallery. A stripped-down version of the WebMynd add-on applies your installed stylesheet whenever you’re on a Google search results page. (You can enable WebMynd’s other features if you like, but they’re turned off by default). Anything that can be manipulating using CSS can be changed with RedesignGoogle; WebMnd offer a web-based CSS editor for creating and previewing your designs, but you’re free to use your preferred tools — just paste your stylesheet into the editor when you’re ready to apply it to your own searches and publish it to the Gallery.
