Improved Pi-A-Sketch video

Mighty RaspberryPi drawing

I've made a new video of the Pi-A-Sketch:

Not quite as circular

One thing you will notice is that the circles have a kink on each sides (at the interface of each quadrant). With time, it appears that the compensation factor for the slop has to be adjusted. I've demoed this so much that I guess there is a little less slop than there was before. That is quite curious. It also means that I will have to add a calibration mode, perhaps a little jumper or switch, and when the Pi boots, it will run the calibration mode instead of the drawing mode.

This will definitely increase the code in a significant way (currently less than 200 lines of Python)
