"Over the last couple of weeks I've enjoyed playing with the Arduino hardware prototyping board. This week's open-sourcing of the Second Life client came at exactly the right time for a new experiment.

Here's a video demonstration (people reading the feed, start your web browsers). On the left you'll see an Arduino reading analogue values from a potentiometer and feeding the results in via the USB-serial interface to my Mac. On the right, you'll see a modified version of Second Life that is feeding those values in via my avatar's chat channel. An object in the Second Life world is reacting, with perhaps a half-second lag." - Link.
