Hi all,
I've written up a blog post with some playing around a friend of mine and I did today:
I recorded sensor data from my android phone and plotted it with d3. I also tried integrating the acceleration to recreate the 3D path my phone took. the 3D result is a bit lacking in scientific rigor, but I thought the community might be interested in how quickly you can play with visualizing this kind of data (and this data is available personally by many people).
I also gave a shot at using cubism by making a custom metric from the JSON, which may be interesting to some.
