visual programming

Introduction
I tried to host this session last year but had some issues that prevented me from attending.

Description
on the official website, vvvv is described as:

"a toolkit for real time video synthesis. It is designed to facilitate the handling of large media environments with physical interfaces, real-time motion graphics, audio and video that can interact with many users simultaneously."

I would hope to do some demonstrations on physical interfaces (sliders/knobs/motion sensor), motion tracking, marker tracking, real time motion graphics, wii-mote connectivity, as well as a basic feature overview and introduction to its visual programming paradigm (similar to GEM, pure data, max/msp, etc). You can also do a lot of fun stuff with a webcam, so I'll probably bring one of those too.
