Big.com is a spin-off (the Web is dangerously moving towards Hollywood) of Snap.com but mainly for the elderly, semi-visually-impaired, and people who simply like big fonts (Web 2.0 web designers come to mind). The search results come from Ask/Teoma and as much as I like the idea, it's not something of my taste although some people may use it (if the results came from Google and the smallest font-option was a little smaller then I'd be saying something different).
