Visual Search

Interesting search idea at like.com.  You click on the visual search button, and draw a rectangle on an area of the product and then search for similar items based on shape or color of whatever is inside the rectangle you drew.  I'm not sure how accurate the search is, but it's nice to see attempts at changing and/or improving the way we look for things. 

I wish they had something similar for music, you know, when you can't remember the name of a song but you know the melody, a search engine could give close matches for that melody...
