Here's today's tantalizing hint at things to come.
I've succeeded at getting data all the way from a little knob I'm turning
to the Arduino, to Processing, to Blender via the OSC protocol facilitated by Python's Simple OSC and Processing's oscP5.

What does that all mean?

It means I have the alpha prototype for a real time digital puppetry
performance and capture system.

And it's the seed for helping Blender Game Engine developers obtain
any sort of interesting input for their games.
