During Google's extended edition opening keynote this morning, there was a distinctive lack of skydiving. However, developers showed off lots of interesting things, including functionality highlighting the easy, real-time syncing of data across multiple instances of the Chrome browser -- whether on smartphone or tablet or desktop. The on-stage demo was a simple slot car racing game but, out on the I/O floor Google had a somewhat more advanced implementation: Map Dive. Running on seven separate instances of Chrome and relying on a 3D camera, Map Dive lets you experience the Maps API from a rather elevated perspective. Join us after the break for an arm-waving demo.
