ScribbleBot the Artistic Drawing Robot

This year at Maker Faire Orange County, I helped out at the drawing robot exhibit and we spent a great deal of time re-soldering each robot; now I've spent the last 3 or so days working on this fun little project to make the perfect 'ScribbleBot"

Here's a list of the parts required:
1x 6mm*10mm DC3V 3.7V Micro 610 Coreless Vibration Vibrator Motor
1x Coin Cell Holder for 20mm*3.2mm Coin Cells (ie - Philmore No.BH2032)
1x CR2032 battery
1x 12x8mm DC30V 1.5A Small ON-OFF 2-pin Push Button Switch (14.4mm CC hole dist)
1x 20mm wire
3x 8.5mm diameter pens

Here's a vid of it in action and a recount of the prototyping process:

Be sure to use a tiny file or knife to gently remove that little triangle shaped support piece under the Lego pip before attaching anything.  

If you found this useful, it would bring me great joy to see your work - so be sure to share. :)
