Tired of Google's white homepage? Starting today the search giant is letting users customize its famously spartan home page with photos of their own or from a public gallery featuring the works of professional artists, by clicking a link on the bottom left corner. This is a major shift in the company's design philosophy. Amid a storm of criticism online, Google has decided to cut short its 24-hour experiment and stop loading the background image by default, leaving the option open to anyone who wants to use it.
