Google Guitar

In Google's main page has a playable logo shaped as a guitar. Its actually one of the seamless complicated experiences that I have had on the web. What was amazing to me was how fast the application loaded and how accurate the experience is when playing the google guitar. It sounds how i would expect a guitar would sound and strings vibrating like a guitar, I hardly get impressed anymore and this did impress me.
