The magic wand project is quiet meta because unlike most other connected devices that record sensors over time, we're recording data at any time point we like, to record how we improve the device fidelity for the motion.

The drawing is not our end goal, it is sweet though. It is a measure to visualize how the device has moved. So that we can debug late when we want to make a certain gesture, which brings us to the next part:

Tom suggested this device to be paired with the light-hue device -- to activate it with certain gesture from the magic wand.
