Dynamic Search Interface

This interface uses a series of sliders that let users specify their search criteria. The control on the left automatically update the results on the right. There is an interesting treatment of the results into relevancy groupings - with the top five getting bold color treatment, the next 10 getting gray shading and then next 10 on a white background. I'm not sure how well this works visually, as to me it appears the page contains three separate elements rather than a single, ranked list.
