Sketches of Co'ordinates / Speed / Altitude

I really like data visualization so after discovering that my MacBook has inbuilt accelerometers I decided it would be cool to see whether I could use these to map a cars journey. For this I used Processing, a Python library for interrogating the MacBook's accelerometers called PyAppleSMS and an external Bluetooth GPS unit.

The A24 mapped for altitude and speed
2 roundabouts mapped for roll

The image above shows two roundabouts. The lines coming off at right angles show the roll of the car (using the MacBook's accelerometer. Speed (using the GPS unit) was shown using turquoise for fast, slowing to green and orange for slow.
