Google's logo in 1999
Forget about the layout of most search engines, forget about the top 10 results, forget about different interfaces for images, news, maps, videos. Imagine that Google starts from the beginning, puts the beta sign next to the logo and reinvents itself.

How would you imagine a search engine if you tried to ignore everything you've seen before?
"Phrase in English: You're invited to try an experimental version of GOOGLE search.Translation Help: This is the promo for Google beta."
