Releton Search, an adjustable Google/Yahoo hybrid

This is kind of cool, although not obviously incredibly useful. Releton provides you with a typical search entry box and results page; it's results are a combination of Google and Yahoo results. What's interesting about it is the slider at the top of the results page which allows you to control the mix; it starts at 50:50 and updates the results in real time (ala AJAX) while you slide it back and forth to adjust the weighting between Google and Yahoo.
