Inside the 3D experience you can compose your own music, play around inside a photo booth (web cam required) and make your own movies with a Zoetrope. You will also face a tornado. If you survive you will get to see an exclusive unreleased clip of the upcoming movie. Take a quick watch of what the experiment has to offer.
Google mentions that for the best experience you will need an up to date computer built to handle intense graphics. When we launched it for the first time we could choose speed or graphics. So even a slightly older computer should be good to go, you just won’t get the extremely beautiful graphics. Of course they also suggest using Google Chrome to do it. Along with the PC based experience, you can also open it up on your phone or tablet using the Chrome Browser mobile app.
